Miley's Totally Weird AMAs Purrformance

Miley's Totally Weird AMAs Purrformance

Fresh from celebrating her 21st birthday, Miley Cyrus walked the red carpet for the AMAs in LA on Sunday. Surprisingly, she was covered up in a white suit with safety-pin details for the event and skipped sticking out her tongue while stopping for photos. Miley also had her dad, Billy Ray, by her side on the red carpet when she wasn't posing solo. While she wasn't up for any awards tonight, Miley hit the stage to perform "Wrecking Ball" and — following in her recent pattern from the MTV VMAs and EMAs — wowed the audience by singing in sync with a giant digital cat behind her. Miley took the animal theme one step further by wearing a skimpy two-piece printed with kitten faces.

This is just the latest in Miley's big year — get caught up on her crazy evolution and the most memorable comments she's made in the last few months.
