Sean Preston Federline

Britney Spears was joined by her sons, Sean Preston Federline and Jayden James Federline, for a stop at Starbucks on Saturday in LA. Britney also brought her pup, Hannah, along for the fun. Absent from the family outing was her fiancé Jason Trawick, who celebrated his 41st birthday Saturday as well. Brit was sure to wish Jason a happy birthday on Twitter, though. She shared a picture of a young Jason blowing out candles on his cake many birthdays ago, saying, "There are definitely going to be a few more candles on your cake tonight. Happy birthday baby, love you so much!" Brit was able to celebrate with her husband-to-be during a break from wrapping up her X Factor-judging duties — the show winds down with the final cut this week.

Britney Spears and Jason Trawick took Sean Preston and Jayden James to the California Music Academy in LA on Saturday. The foursome spent the weekend together during a break from Britney's busy schedule. She's been working on X Factor, but with only four contestants left, the season is winding down, and Fox has yet to confirm that she'll return for another season. Britney also recently released her new track with will.i.am, "Scream & Shout," and the accompanying video and celebrated her 31st birthday. It's been a big year for the singer — does she get your vote for favorite female celebrity of 2012?

Britney Spears made a trip to Target accompanied by her boys, Sean Preston and Jayden James, yesterday in LA. Britney's sister, Jamie Lynn Spears, also joined them for the family fun, during which they all enjoyed beverages from Starbucks. Britney and her sons are making their Sunday shopping outings somewhat of a routine. Last weekend, Britney, Jayden James, and Sean Preston swung by Petco to pick up pet supplies and they also made a stop for drinks at a Coffee Bean & Tea Leaf. She had a busy week leading up to the Thanksgiving holiday with the release of her track with Will.i.am, "Scream & Shout," last Monday. We'll get to check out the video for the hit on Wednesday, when it debuts during The X Factor.

Britney Spears and her sons, Sean Preston and Jayden James, made a McDonald's run in Calabasas, CA, yesterday. They wrapped up their weekend with fast food as Britney preps for another exciting week on the small screen. The X Factor contestants will be divided into groups and visit their judges' homes, including Britney's in LA, as they continue boot camp in the coming episodes. It's all leading up to the live portion of the competition, which kicks off in November. The show is never far from Britney's mind, though, since she tweets about it each week and shared birthday wishes for fellow judge Simon Cowell yesterday. Britney also talked about her experience during a recent interview with our I'm a Huge Fan Winner — watch the whole I'm a Huge Fan: Britney Spears series now!

Britney Spears had her plane reading in hand as she and Jason Trawick arrived at the airport in Maui with Sean Preston and Jayden James yesterday. The foursome was heading out of the Aloha State after a weeklong vacation in the islands. The group celebrated the Fourth of July during their trip and also fit in plenty of pool time. Britney wore a purple bikini to soak up the sun, while a shirtless Jason showed off his fit physique. Britney will next get back to her X Factor duties with the final round of auditions taking place in North Carolina tomorrow and Monday.

Britney Spears shared a sweet picture of herself in a bikini with her sons, Sean Preston and Jayden James, in Hawaii yesterday. She added, "Getting ready for some pool time! Having a blast." Britney was later spotted heading to her hotel pool with a shirtless and very tan Jason Trawick and her boys. Britney and her fiancé traveled to the islands with Sean and Jayden on Monday, and they've been soaking up the sun ever since. The foursome celebrated the Fourth of July together yesterday and captured the holiday fun with a sweet snap of them all wearing leis. They were just a few of the many stars — from Zac Efron to Jessica Alba to Heidi Klum — marking Independence Day on the beach.

Britney Spears touched down in Hawaii with her sons Sean Preston and Jayden James as well as fiancé Jason Trawick yesterday. The tropical getaway comes during a break from Britney's X Factor duties. She's been traveling across the county since May with stops in Texas, Missouri, California, and Rhode Island already, but her work on the road isn't over just yet. Britney and her fellow judges, L.A. Reid, Demi Lovato, and Simon Cowell, still have one more visit to make, in North Carolina, before they wrap up the auditions. That taping happens next weekend, so it looks like Britney has a whole week to spend relaxing with her family.

Britney Spears and her fiancé, Jason Trawick, hung out on the beach in Malibu with Sean Preston and Jayden James on Saturday. Britney brought her camera for the sandy visit, though she also got in front of the lens to pose for a photo with her boys. The foursome took advantage of Britney's downtime from her X Factor duties, with her latest stop taking place last week in San Francisco. The judging crew, including Simon Cowell, L.A. Reid, and Demi Lovato, will continue their talent search with visits to Rhode Island and North Carolina in July. Fans will have a chance to watch all of Britney's hard work on display in September, when The X Factor premieres on Fox.

Britney Spears touched down in LA on Saturday with her sons, Sean Preston and Jayden James Federline, as well as fiancé Jason Trawick. A private jet took the family home from Las Vegas, where Britney and Jason hosted a party on Friday evening. There were multiple causes for celebration, including Jason's 40th birthday. The bigger news, however, is that Britney and Jason are engaged! She tweeted afterward: "Tonight was one of the most magical nights of my life. Such an amazing time with my new fiancé and our closest friends and family." The bash offered a chance for us all to get a glimpse at Britney Spears's Neil Lane engagement ring. Neil spoke about working with Jason on designing the ring. The jeweler spoke glowingly about Jason's affection for Britney. Neil said: "He’s deeply in love with her. Britney is his princess, and he is her knight in shining armor. Jason’s protective of her. He adores her. Every good fairy tale needs a princess, and now Britney has a ring fit for a princess!”

Her ex-husband, Kevin Federline, has also weighed in on the development. It seems Kevin approves of his sons Sean and Jayden's new stepdad-to-be. Kevin Federline likes Jason and recently said: "I've spoken to him quite a few times as of now. He seems like a really good guy. The kids speak highly of him, [and] her family loves him."

Britney Spears held hands with Jayden James and her boyfriend, Jason Trawick, was hand in hand with Sean Preston yesterday as the foursome strolled Paris. Britney plays in the City of Lights tomorrow night as she continues on her European tour. The boys have joined her on her travels, and her parents even made a pit stop in Croatia when Britney was there last weekend to visit with their daughter and grandkids. Sean Preston and Jayden James were on stage with Britney at her show there, at the Arena Zagreb, waving to the fans after mom finished performing "Till the World Ends" for the cheering crowd. The family will remain on the road through December, but they're taking time out to explore the sights. Britney and Jason even teamed up to shoot a new music video for "Criminal" during their time in London last month.
