Rihanna embraced the warm weather in LA Thursday, showing off her long legs in a short floral skirt. After her American Idol performance, she called in for an interview on Ryan Seacrest's radio show where she officially called Dodger Matt Kemp her boyfriend. Rih also gave Ryan the scoop on Katy Perry's wedding to bridezilla Russell Brand, which will apparently take place in India, and her upcoming tour with Ke$ha. With "Rude Boy" currently number one on the charts Rihanna is knocking down the competition but she'll need to continue racking up votes to reign as queen of her PopSugar100 matchup against Carrie Underwood. Round one voting closes Wednesday so make sure to get in your picks for a chance to win a hot Chanel bag!
