Rihanna started tonight's MTV VMAs with a rowdy performance of her new song "Cockiness," and host Kevin Hart was on stage afterward to start the jokes coming. He verged into some potentially awkward territory when he tried to end the feud between Drake and Chris Brown, both of whom went on to win awards later. Kevin even leaped to Kristen Stewart's defense in his opening riff about mistakes. Katy Perry popped up to present the first award, best pop video, to One Direction. One Direction also later claimed best new artist. Robert Pattinson, meanwhile, joined his Twilight buddies Peter Facinelli, Taylor Lautner, and more to debut a new clip from their upcoming Breaking Dawn Part 2.

As for the performances, Miley Cyrus introduced Pink, who put on a boisterous show. Frank Ocean, welcomed by Zoe Saldana, had one of the night's most moving onstage appearances and was followed by Lil Wayne, One Direction, and Green Day. Alica Keys, who took in the fun alongside husband Swizz Beatz and their son Egypt, debuted her new song "Girl on Fire." Taylor Swift also wore her signature red to belt out "We Are Never Ever Getting Back Together." The final Moonman went to video of the year honoree Rihanna for "We Fell in Love." She made a triumphant speech after brushing some dirt off her shoulder — make sure to check out who wore what on the red carpet and the full list of 2012 MTV VMAs winners.

Today is Beatles Day, a day to mark the Fab Four's rise to fame. The boy band phenomenon all started with the "mania" surrounding The Beatles, and since the guys from One Direction — the latest UK boy band to hit the scene — have now been made into action figures, it looks like everything has come full circle. Over the past 50 years, there have been a number of synchronized, harmonizing boy bands, each of them just a bit different from the last. Can't get enough of the craze, or hoping to relive your favorites from the '90s? From The Beatles to One Direction, here's a look at the most popular boy bands of all time.

The guys of One Direction, Zayn Malik, Niall Horan, Harry Styles, Liam Payne, and Louis Tomlinson, let loose off the coast of Sydney today. The group is fresh off an SNL performance over the weekend, and seems to be celebrating with some much-deserved downtime before embarking on their Australian tour. The British-Irish boy band rose to fame following a third place finish on the seventh season of the UK's X Factor, and since then they've been signed to Columbia and Simon Cowell's own Syco Records.

The group is taking the music charts by storm around the globe. Their album, Up All Night, is currently ranked in the top 10 on iTunes and their latest single "What Makes You Beautiful" has been teetering between the number one and two positions on the digital singles chart. In addition to dominating the online music industry, the band is also selling out shows on multiple continents. The Australian leg of their tour is completely sold out, and tickets for their Dec. 3 Madison Square Garden concert went on sale Friday and were gone in less than an hour!
