She is often seen hitting the gym in New York City when she's not working or taking care of her daughter Suri Cruise.
And it seems that Katie Holmes has recently shed several pounds off her frame.
The
34-year-old revealed her bony back as she attended the Metropolitan
Museum of Art's Costume Institute Gala on Monday night in New York City.

Katie's not known for her daring fashion choices on the red carpet.
But as she attended the Met Ball on Monday night she seemingly decided to think outside of the box.
However,
the 34-year-old's choice of gown for the Punk: Chaos to Couture themed
bash could only be described as a fashion faux pas.

The actress wore a white Francesca Costa gown, which was reminiscent of toilet paper as she glided down the red carpet.
The dress in question was a halterneck cut, showing off her back and shoulders.
She teamed the ensemble with a pair of white sky high stilettos that were a little too matchy matchy.

She attended the gala in 2009 with her now ex-husband Tom Cruise and wore a red strapless dress and bright blue shoes for the occasion.
Since the couple split last year, Katie has been keeping busy as a single mother to her daughter Suri as well as taking on Broadway and film roles.
She's currently been working on Mania Days, which is the star's second film since splitting with Cruise - the father of Suri.

After an almost complete career hiatus during the marriage, Katie is certainly back having done a stage show and also she currently has three films in production.
She has been filming the movie since the begging of the month alongside its other star, Canadian actor Luke Kirby, who is relatively unknown outside of independent film circles.
In the Spike Lee production, Katie stars as a manic depressive poet who falls pregnant to a manic depressive rapper.
The film is set to release in 2014.
