Several stars have stepped out in crazy high heels lately, but no spring footwear is as attention-grabbing as Prada's "Tail Light Flame" heels.

And two of the most fashion-forward celebs dared to rock the colorful patent leather creations (which retail for around $1,450). 

Fergie coordinated her yellow-and-green wedges with a BCBG dress and matching Adolfo Sanchez jacket at the Don-A-Matrix party in Beverly Hills March 17.

But it was Katy Perry who first worked the red-and-yellow stiletto version with a pink Miu Miu print dress and pale blue coat during Paris Fashion Week last month.
