Rihanna Rocks the House of Blues for Charity

After dueting with Coldplay at the Grammys, Rihanna lent her voice to a charity gig at L.A.’s House of Blues, with Deadmau5, Calvin Harris, and Sebastian Ingrosso of Swedish House Mafia on the bill.

Although she was only on stage for seven minutes, the blonde beauty thrilled concertgoers who shelled out between $250 and $1,000 at the fundraiser to benefit Children’s Hospital Los Angeles. She opened with “Where Have You Been” and joined Harris for “We Found Love” as confetti fell from the sky.

RiRi later celebrated her Grammy win for Best Rap/Sung Collaboration (“All of the Lights”) at Greystone Manor Supperclub in West Hollywood with Drake, Ameriie, Tyga, and her brother Rorrey.
