Katy and her itsy bitsy teeny weeny yellow (well, white actually) polka dot bikini took their talents down to South Beach last week and she showed off her latest hair color. Check it out after the jump. (By the way, this looks like it may be the hotel I stayed in 2 weeks ago in Miami which makes me oh so sad because I’m dying to meet Katy!! *Sigh.)
