Yolanda Foster: Sheer Happiness

Yolanda Foster showed up to the 'Real Housewives of Beverly Hills' premiere party Thursday night in a dress that gave a pretty clear message she's back on the market. 

Foster, who's been battling Lyme disease, looked radiant and was all smiles days after announcing her split from her husband of 4 years, music producer David Foster

She's said she's heartbroken over the split but you couldn't tell from her game face ... and body.
