Rihanna rocks South Beach until 4 a.m.

While her outfit may have been somewhat half-assed and according to some so were her vocals, Rihanna had a fabulous night following her gig at the free Pepsi Fan Jam concert on South Beach, partying at Mansion and SET with a gaggle of galpals until the we hours of the a.m. Wearing a more completed outift this time--a skin tight beige dress, Ri-Ri sat front and center at her party at Mansion where she sipped on Grey Goose and grace juice and danced to songs by Jay Z and Drake as the masses of athletes clamored to catch a glimpse of her. At around 1 a.m., the Mansion team presented her with a cake in the shape of a golden Grammy to congratulate her on her two Grammy wins, out of which she took a big bite. Shortly after, she and her posse made their way to SET where they snuck in through the back entrance and set up shop at a table not far from Jermaine Dupri. Sipping on Grey Goose and Ace of Spades champagne, Grammy’s golden girl giggled with girlfriends throughout the night, dancing on top of her table to songs by The Ting Tings and Journey before calling it a night around 4 a.m. and heading back to her hotel.
