RIHANNA & FRIENDS HIT GUCCI UNICEF PARTY

New spokesmodel Rihanna along with some of her celeb friends hit up the Gucci Tattoo Heart Collection benefit Wednesday. The collection will fund Gucci's 4th annual UNICEF campaign - 25% of the proceeds will go to UNICEF programs for people with HIV/AIDS.

Of course Rihanna was decked in Gucci

Hey...Madonna showed up in a frilly, feathery frock by Louis Vuitton

MJB showed up...Is that faux fur?

Timbo came through as well.

Later in the night, RiRi did a switch-a-roo and got into something a little more comfortable. Love this dress. She even showed off her new tribal tattoo. "It represents strength and love" she told reporters. She got the exotic-looking tat while in New Zealand for a recent tour date.
