It was an all-ages party last night at the 2012 Teen Choice Awards, and we've got the pics to prove it. "Skyscraper" singer and "X Factor" judge Demi Lovato hosted (looking gorge in a crazy-long ponytail), helping award some of today's most popular teen idols with giant surfboards that will likely collect dust in their garages for years to come. 

Justin Bieber continued to reign supreme, snagging four TCAs: Choice Male Artist, Choice Single by a Male Artist (for "Boyfriend"), Choice Male Summer Music Star and Choice Male Fashion Icon. (He's a visionary, ladies and gents.) His girlfriend, Selena Gomez, and her backup band, The Scene, nabbed Choice Music Group, while country queen Taylor Swift dominated most of the remaining music categories: Choice Female Artist, Choice Single by a Female Artist (for "Eyes Open"), Choice Female Country Artist, Choice Country Song ("Sparks Fly") and Choice Movie Voice for her role in The Lorax—we really hope she likes surfing. Oh, and those adorable British boys One Direction didn't do so bad either: They nabbed Choice Summer Music Star, Choice Breakout Music Group and Choice Love Song for "What Makes You Beautiful."

The Teen Choice Awards also saw No Doubt's return to the Teen Choice Awards stage after nearly a decade away, which was not only awesome, but gave you a panic attack when your niece asked who who they were. Gwen & Co. dominated their first live performance of their first Push And Shove single, "Settle Down." Justin Bieber also hit the stage and brought out Big Sean for his futuristic medley of "Boyfriend" and "As Long As You Love Me." Flo Rida and Sia got rowdy on "Wild Ones"—shout out to Taylor Swift's booty poppin' during his performance—and Carly Rae Jepsen closed the show by shoving "Call Me Maybe" down our throats one more time. (JK, I still love it.)
