Katy Perry - AMAs 2013 Red Carpet

Katy Perry shows off her flower power in Oscar de la Renta while hitting the red carpet at the 2013 American Music Awards held at the Nokia Theatre L.A. Live on Sunday (November 24) in Los Angeles.

The 29-year-old singer will be opening up the show with a performance of her new single “Unconditionally.”

“A 🌸clue🌸 to the theme of my AMA performance this evening! I will be OPENING the show & taking you on a trip!!!” Katy tweeted along with a photo of her microphone. See it below!

Katy is not nominated for any awards this year, but we bet she will be next year with her latest album Prism!

FYI: Katy accessorized her dress with Charlotte Olympia shoes and an Olympia Le Tan bag.
