Rihanna kept the dominatrix gear to a minimum performing in NYC last night to benefit her charity for children with cancer, Believe, and DKMS research. Not only did she perform for the kids, but she also stopped to pose and sign autographs for them — such a little sweetheart. There was one audience member in particular who must have been especially proud to see her work on stage and with the kids: Chris Brown was spotted sneaking out with Rih after the show. I guess there was no duet in the cards last night, but there's always another opportunity for the inseparable duo.

Britney Spears examined her slimmed down and toned up body while enjoying her favorite vice outside her house yesterday afternoon. Brit's been hard at work improving her life and last night she was inspired to change the lives of others too. Apparently, while watching Idol Gives Back she was so saddened by the stories of kids dying of Malaria in Africa that she called and donated $25,000 of her own money (with permission from Jamie). If all goes well, maybe next year at this time she'll be one of the performers on the stage helping to ask for donations from viewers like her.

Fool's Gold came and went pretty quickly stateside back in February, but Kate Hudson and Matthew McConaughey were reunited once again for a premiere in London today. Kate was gorgeous from the neck up, but a little lost in that fabric from her crazy green mermaid dress. Luckily we can count on MM to serve as simple eye candy — even if he looks a little wax-figurish. Though we didn't exactly love the film, we always love the opportunity to see these two beautiful people getting playful on the red, or more appropriately for a beach movie, blue carpet.
