No more standing under her umbrella! Rihanna, who had been reclusive after former flame Chris Brown allegedly assaulted her in February, stepped out stronger than ever at the DKMS 3rd Annual Linked Against Leukemia Gala at Cipriani 42nd Street in New York on May 7. “You tell me!” the stunning songbird smiled when In Touch complimented her beauty at the swanky soiree. Rihanna later took the stage to present an award to Isabelle Huurman, a 6-year-old who pleaded for bone marrow donors to save the life of her cancer-stricken best friend, Jasmina Anema. “I am so honored to be here to present the Links of Love Award to Isabelle for all she has done to save her best friend. Thank you, Isabelle! You’re an incredible best friend — the kind we are all lucky to have,” the starlet told the glowing little girl. Perhaps her big heart and new beau Negus Sealy are helping Rihanna to move on.
