Exhausted! Katie Holmes looked worn out as she left a gym in Brentwood, California today
Katie Holmes certainly worked up a sweat during her visit to an L.A. gym yesterday.
The 32-year-old's purple T-shirt was drenched with perspiration as she left the fitness studio in Brentwood, California.
With her damp hair scraped back, she looked worn-out as she shuffled to her car in a pair of Ugg boots after changing out of her sneakers.
The actress' skinny frame has been the subject of magazine headlines in the U.S. in recent weeks, but she clearly has no intention of slowing down her exercise regime.

She was in the city to promote her new film, Don't Be Afraid Of The Dark, and work on her fashion label Holmes & Yang.
Katie is expected to soon start filming Responsible Adults, romantic comedy starring Chace Crawford, about a guy who realizes that his crush was his babysitter 15 years ago.
Her husband Tom Cruise is still working on his upcoming musical, Rock Of Ages.
