Rihanna has been keeping a low profile since she was allegedly assaulted by Chris Brown, and recently she headed down to Mexico for some rest and relaxation. She rented a private villa over the weekend to celebrate her 21st birthday with a few friends. On Saturday, Rih was spotted hanging out poolside, looking as hot as ever in her white bikini. Chris's court case has been postponed due to lack of evidence, but hopefully Rihanna's getaway in Mexico is helping to keep her mind off the incident for a while.
