PHOTO: Rihanna Leis Low in Hawaii
The 21-year-old singer slipped undetected through LAX at the start of her latest getaway, according to a source, and has been staying at a hotel on the Hawaiian island of Oahu.
Rihanna has been traveling a lot since allegedly being assaulted by Chris Brown, 19, in February. After a solo trip to Mexico, she and Brown reconciled and spent time together in Miami and L.A. In mid-March, Rihanna hit N.Y.C. – sans Brown. At the time, a source told PEOPLE, "She is looking forward to getting back to work and focusing on her career again."
