Bright lights and late nights. Hollywood’s best were out and about yesterday, and couldn’t get enough of the cameras.

Today’s installment of Celeb Snaps offers up a heaping helping of promotional tours, fitness fanatics, and set visits. Jay-Z, 42, stopped by the Barclay’s Center to get ready for his upcoming tour after debunking rumors that he and Beyonce are expecting.

Who else was caught in today’s edition of Celeb Snaps?

Kesha, 25, was on the set of her latest video, for the single ‘Die Young’ in Los Angeles on Wednesday. The pop star showed off some killer curves and looked very futuristic in a grey one-piece leotard and boots.

New mommy Hilary Duff, 24, was working off the last of the baby weight at her West Hollywood gym on Wednesday. Quickly getting back into beautiful shape, Duff is looking better than ever.

Kourtney Kardashian, 33, has been a busy lady since landing in Miami to film her spin-off Kourtney & Kim Take Miami. Kardashian found some time to fit in a beach-side workout with her two friends by her side for support.
