The 2011 AMAs: Backstage & On the Red Carpet

By

A wet and chilly night in Los Angeles couldn't stop music's biggest stars from heating up the red carpet at the American Music Awards Sunday night.

ET's special correspondent Christina McLarty was front and center for the festivities, catching up with Taylor Swift just moments after her Artist of the Year win (one of three awards for the night).

"I'm so happy and so thrilled and excited," beamed Swift. "I just didn't see it coming at all, and I'm just so so unbelievably thankful to the fans."

Humbled as always, Taylor explains that although she just snagged three huge AMA honors (Country Female Artist, Country Album for Speak Now, and Artist of the Year) she can't help but approach each award like it's "the first."

"You're never guaranteed that next nomination or that next sold-out show. That's never a guarantee. To get these things and to continue to get these things, I celebrate each one of them like it is first time it's ever happened because you never know what's going to happen and I'm just so happy!"

Watch the video for more of Taylor's post-win interview, including a few words with another big winner of the night, Nicki Minaj.
