Rihanna was spotted in NYC last night at The Plaza to celebrate her Gucci Tattoo Heart Collection to benefit UNICEF.  She changed her look several times through the night, all of them stunning.  This is definitely Rihanna's year. Other celebs in attendance include Madonna, Mary J. Blige, Timbaland, Adrian Grenier and more. Pics: Wireimage In case you missed it, check out her new music video "Rehab" ft.
