Rihanna’s Post-Idol Night on the Town

She’s always on the go, and last night (April 14) Rihanna was spotted out at Osteria Mozza in Los Angeles.

The “Take a Bow” songstress looked super sexy in a cleavage-baring red dress with matching heels as she strolled into the hot spot.

Ri-Ri also hit up the swanky Voyeur nightclub where she partied with one of her favorite gal pals, Katy Perry.

Earlier in the evening, Rihanna dropped by the “American Idol” stage where she performed her hit song “California King Bed.”
