Hilary Duff tights t-shirt Beverly Hills

She certainly moves fast!

Hilary Duff hit the gym in Beverly Hills on Monday afternoon, and the 26-year-old starlet is back on the west coast after shooting her new pilot in NYC last week and then jetting of to the Bahamas.

The TV Land pilot, called Younger, is about an ambitious 20something (Duff) who strikes up a friendship with her co-worker Liza (Sutton Foster), but fails to realize her new pal is nearly a decade older. Sounds perfect for the former Disney starlet!

Duff jetted off to the Caribbean last Wednesday, and she was joined by estranged hubby Mike Comrie, and the two even posed for a photo with their son Luca. Hmm, we know their split was amicable, but any chance these two are entertaining the notion of getting back together?
