chaka khan*R&B icon Chaka Khan turned the big 6-0 over the weekend and celebrated with a star-studded birthday bash in Hollywood.

Natalie Cole, Anita Baker and David Foster were at LA’s Yamashiro restaurant on Thursday to help Chaka celebrate the milestone. Her actual birthday fell on Saturday, March 23.

The event also marked her 40-year career in music, and Khan admitted to CBS she was stunned with how fast the decades have flown.

“I don’t know where the time went. I have no idea,” she said. “It doesn’t feel like 40 years! This is fabulous, but it really hasn’t hit me yet.”
