Gwyneth Paltrow got in one-on-one time with her husband, Chris Martin, during a stroll in London yesterday. The rare moment of downtime for Gwyneth came after a busy few months of promoting her new Goop app, as well as wrapping up her world press tour for Iron Man 3. Along with working on her own business ventures, she took time out for a good cause earlier this week. Gwyneth signed the inside of an Audi RS 6 car that will be auctioned off at Elton John's upcoming White Tie and Tiara charity ball, which benefits AIDS research.

Gwyneth also got to catch up with her friend Taylor Swift, who stopped by her London home last weekend. In typical Gwyneth fashion, her quiet time is coming to an end since she is headed to the States to pick up an honor in Chicago tomorrow. Gwyneth will be presented with the Renaissance Award by the Gene Siskel Film Center of the School of the Art Institute of Chicago in the Windy City on Saturday.

Halle Berry covered her baby bump in a sheer black dress to hit the red carpet alongside her fiancé, Olivier Martinez, for the Les Toiles Enchantées charity event at the 2013 Champs-Élysées Film Festival in Paris yesterday. Halle was the guest of honor for the charitable evening, which brings films to hospitalized children in France, and Olivier held a special post at the event as well since he is serving as the festival's honorary president this year.

Halle and Olivier stepped out for the red carpet affair after he shared exciting news during his press duties at the festival earlier this week. Olivier confirmed that Halle is pregnant with a boy, and the couple appeared to be delighted about adding a son to their family, which includes Halle's daughter, Nahla Aubry. Although they are currently spending time in Olivier's native France, he made it clear that his son would be American. He said, "My son will be an American, but I remain French." Halle is just one of the many expectant mothers in Hollywood — check out all the pregnant stars!

Sandra Bullock donned a sexy black gown to premiere her latest film, The Heat, in London today. She walked the carpet solo since her pal and costar Melissa McCarthy is currently on location in North Carolina filming Tammy. Sandra did have the company of director Paul Feig, who is best known for his work on Bridesmaids, as well as her costars Jamie Denbo and Jessica Chaffin. Although Melissa missed out on the trip overseas, she did get to debut the film at CinemaCon with Sandra earlier this year. We were on the ground at CinemaCon back in April to catch up with the hilarious duo, who shared details about their "love connection" off screen. Sandra will soon bring The Heat back to the States since the comedy is set to hit theaters in the US on June 28.

Taylor Swift stunned in a white Emilio Pucci dress to step out for the Fragrance Foundation Awards in NYC last night. She was joined by Connie Britton and Jessica Szohr, who both took the stage for the evening's festivities. Taylor had a lot to celebrate since her scent Wonderstruck Enchanted picked up the honor for celebrity fragrance of the year. Taylor's olfactory success won't stop with last night's award, since she recently debuted her newest scent, Taylor, earlier this month. We were on the red carpet to chat scents with Taylor, Connie, and Jessica, so stay tuned to POPSUGAR Live! for the interviews.

While Taylor was busy getting recognized in the fragrance world, she made headlines for taking home a trophy at another award show. In Kanye West's controversial interview with The New York Times, which was published on Tuesday, he may have directed a quote or two toward Taylor in relation to his interrupting her acceptance speech at the 2009 MTV Video Music Awards. When asked about his concept of regret, Kanye revealed, "If anyone's reading this waiting for some type of full-on, flat apology for anything, they should just stop reading right now."

Justin Timberlake stepped out for the launch of the new Myspace held at LA's El Rey Theatre last night. It was a big night for him since he is an investor in the social media platform, and had a big role in revamping the site, which now aims to support artists and the music industry. Get the detail's on Myspace's new design transformation to see if it's worth checking out. Also showing her support was Miley Cyrus, who drew attention for her interesting ensemble that included a crop top paired with a sweatpants-and-jeans combo. The event brought out plenty of other stars like Olivia Wilde, Ashley Tisdale, and Dianna Agron. Kelly Osbourne, who had her boyfriend, Matthew Mosshart, by her side, was also in attendance along with Jennifer Morrison and Vanessa Hudgens.

The festivities included a live performance by Pharrell Williams and Robin Thicke who sang their hit "Blurred Lines." Miley has forged a close bond with Pharrell since the pair have joined forces for work on her upcoming album, so it was no surprise that she joined him on stage during his performance with Robin last night. Along with accompanying him on stage, she showed support for her pal on Twitter, writing, "Big bro killed it tonight. Pharrell!" Miley may be itching to get back to performing since she also hopped on stage to do a bit of twerking during Juicy J's concert over the weekend as well.

Accompanying Miley's interesting outfit was her engagement ring, which was prominently displayed on her left hand despite speculation surrounding a budding romance between her and Justin Bieber. Rumors were ignited when she and Justin were spotted hanging out in LA recently, but Miley set the record straight on The Kane Show yesterday, saying, "I'm engaged."

Tom Sturridge pushed his almost 1-year-old daughter, Marlowe, in her stroller for a walk around the West Village neighborhood of NYC with his fiancée, Sienna Miller, and his mom, Phoebe Nicholls, yesterday.

Tom is winding down from a big weekend at Sunday's Tony Awards, where he was a nominee for best actor in a play for Orphans. Although he ultimately lost out on the honor, Tom had the support of Burberry-clad Sienna and his mom on the red carpet.

In addition to being recognized among his Broadway peers over the weekend, Tom is prepping for another special occasion. On Sunday, he'll celebrate his first Father's Day. We caught up with Sienna last week at her Just Like a Woman premiere in NYC, where she gave some insight as to what her fiancé has to expect. Although she nearly forgot about the holiday due to its alternate date in her native UK, she made up for it with a thoughtful suggestion. Sienna told us, "I will have to do something magical. I'll probably make a mug with my baby's handprint on it for my husband-to-be."

Anna Paquin, who wore a sexy black David Koma dress, was loved up with her husband, Stephen Moyer, at the season six premiere of their HBO hit show, True Blood, last night in LA. The couple were joined by a host of their costars, including Alexander Skarsgard, Carrie Preston, and Joe Manganiello, who had his girlfriend, Bridget Peters, on his arm for the night's festivities. While celebrating the premiere of his latest season, Stephen also revealed highly anticipated details of his private life with Anna. While discussing his upcoming Father's Day plans on the red carpet, he revealed the names of his twins, a boy and a girl, whom Anna gave birth to back in 2012, when he shared that he'd be spending Sunday "hanging out with Charlie and Poppy."

Anna and Stephen were not the only stars to make headlines concerning their private lives since Alexander recently sparked rumors that he was once again romantically involved with his The East costar Ellen Page. Although he fueled the speculation by planting a sweet kiss on Ellen last week, the duo are reportedly "just friends."

Stella McCartney got major star support at her Spring 2014 collection presentation at Jefferson Market in NYC yesterday. Cameron Diaz, who is a close friend of the designer, stepped out for the garden party alongside other fashionable faces such as Naomi Watts, Julianne Moore, and Anna Wintour. Madonna and Amy Poehler also showed their love for Stella, sharing hugs and snapping selfies during the fashionable soiree that withstood the NYC rain. Also on hand to check out the designer's Spring designs were Kate Bosworth, who was accompanied by her fiancé, Michael Polish, and Liv Tyler, who had her dad, Steven Tyler, by her side. Kate and Michael even shared a bit of romantic time during the event, which she revealed on her Twitter account. She captured a picture hugging her beau with the caption, "Loved up with Michael Polish at the Stella McCartney party today."

Since Cameron has been stationed in NYC for her latest project, she was able to show her love and support for her longtime friend Stella, whose designs she wore along with Kristen Stewart at the Met Gala last month. Cameron has been busy on the Big Apple set of her new film, The Other Woman, but she headed East to the nearby Hamptons for a fun day of shooting last week. Cameron showed off her legs in a short sweater and let loose with a glass of wine while filming scenes with her costar Taylor Kinney in the beach community.
