Rihanna might not be an early Christmas shopper, but she made up for it with gusto with a whirlwind last-minute shopping spree at Los Angeles' Grove Tuesday afternoon, PopEater reports exclusively.

The whole affair caused an intense security buzz in Nordstrom's when the heavily under cover Rihanna and a male friend worked their way through the men's department.

"Rihanna did her best to keep it under wraps. She had a hood over her hair, which was blonde, and big sun glasses on," says one shopper. "But there was no mistaking it was her."
