After lighting UNICEF's Snowflake in New York City yesterday, Rihanna was joined by Madonna, Blake Lively, Penn Badgley, Mary J. Blige and Adrian Grenier for the Gucci Tattoo Heart Collection dinner. Rihanna officially launched her collection to benefit UNICEF at the event at Plaza Hotel: check out her most recent video ad here. Wearing a gorgeous mauve dress, the singer had donned a red one-shouldered number for the lighting ceremony, and my girl FabUK wants to know which gown do you prefer?

Rihanna spoke about how Gucci creative director Frida Giannini is helping her realise her dream of creating her own collection. "I love designing. Frida's helping me develop as a designer. We've been collaborating on some designs. We've been doing it together, so far for Gucci, but later on in life I want to become a designer."
