Ke$ha is usually known for her outrageous red carpet fashion (or, you know, drinking her own pee on national television), but for night's American Music Awards on November 24, 2013 the 26-year-old kept things simple and subdued. We know, we're just as shocked.

The "Tik Tok" singer stepped out wearing a black, one-shoulder gown with mega slit, Angelina Jolie-style. She wore her long, multi-colored hair sleek and straight with a middle part. Her look was so un-Ke$ha-like that we almost mistook her for current-day Lady Gaga!

"Animals!! tonight @Pitbull and i are performing #timber for the 1st time LIVE!!! so excited!!" Ke$ha tweeted a few hours before the show.

Compared to last year's ill-fitting pseudo-glam look — a lacy peach number with clunky black heels — we give this ensemble an A+.
