Deaton stunned in a short, low-cut white gown while Kinsey sported a black suit with a white dress shirt.

“So the @TCAs_2014 are insane.......... AH!” the duo wrote on their Twitter page while at the event held at the Shrine Auditorium in Los Angeles.

The singers also shared a photo from the chaotic red carpet. “What it's like on a carpet and inside the teen choice awards!!!” they wrote as the caption. "Tonight was amazing but now... TIME FOR FOOD!"

Kinsey, 22, and Deaton, 23, the winners of season 3 of X Factor USA, are gearing up to release their debut album, It’s About Us, on Oct. 7. The two collaborated with some big names, including Martin Johnson from the band Boys Like Girls, Jason Mraz and John Legend. They worked with Legend on a "really good song" one day before he was to perform at the Grammys in January.

"It was actually a really cool experience to write and meet someone who is about to perform on the Grammys but he's just a normal dude," Deaton said during a recent interview with Yahoo Music. "He's really nice and it was fun to write with him."

The two will also go on tour with Colbie Caillat and Train later this month. See the tour dates here.
