New flick: Katie Holmes looked stunning in a white dress as she attended a press event in Cancun, Mexico to promote her new movie Jack and Jill
Katie Holmes appears to have discovered the fountain of youth.
While promoting her new Happy Madison comedy Jack and Jill in Cancun, Mexico today, she looked more like her Dawson's Creek character, Joey Potter, than a married mother.
Laughter must be keeping her young as the actress grinned and was jovial throughout the press trip and looked stunning in her white hot outfit.
Katie, who is married to actor Tom Cruise, looked radiant in a three-quarter sleeved white mini dress.

She was certainly all smiles while mugging for the camera with co-star Adam Sandler.
The comedy revolves around the comedian's character, Jack Murray, receiving a visit from his much-loathed twin sister, Jill.
He initially tries to avoid spending time with her, but his wife - played by Holmes - forces them to play nicely and they end up realising how much they actually like one another.

Sandler, naturally, plays both Jack and Jill and is in drag for much of the movie.
In addition to Sandler's on-set shenanigans, Holmes can credit daughter Suri to the blast she had on set.
During her down time, the actress spent time with her 5-year-old mini-me, taking time to visit a petting zoo and play with rabbits.

But mum isn't the only person Suri visits on set, Cruise got family visits from his little princess, too.
The little fashionista and her mother most recently visited Tom Cruise on the set of his latest film, Rock of Ages, in Miami.
With Tom, Suri and Adam in her life, it's no wonder Holmes has reason to smile.
