Rihanna made her first public appearance last night since she was admitted to the hospital for dehydration and exhaustion a few days ago. She is recovered and the singer is obviously feeling better by now: “I’m a lot better now… I had a couple days to rest and get rehydrated. I just had the flu and I kept working and I wasn’t getting better so I took couple days off to sleep and I feel great.”We are so relieved that she's in good spirits now. We were worried for a while! She also looked ravishing in a seriously cute white number! She wore an all white and daring gown designed by Adam Selman which she combined with Manolo Blahnik sandals and jewels by Vhernier and Neil Lane. It's so great to see her looking healthy with all smiles! (celebuzz)
