Jen Aniston — you may be busy in NYC promoting your new film, ‘The Bounty Hunter’ — but your new co-star, Heidi Montag is hard at work on the set of the new film you two are doing together.

Heidi Montag tweeted that “I just had THE BEST day of my life filming my first comedy movie!!!!! It was beyond what I could have ever dreamed!!!!!” She’s been cast along with Jen Aniston, Brooklyn Decker and Nicole Kidman in the new Adam Sandler romantic comedy about a man who enlists the help of a woman and her kids to land the woman of his dreams.

Heidi was cast in the film, called Just Go For It to play herself on March 10th and tweeted, “This is one of the best days of my life” !!! She’s been tweeting her excitement  —  A LOT — for the past few days: “Having my fitting for my upcoming debut movie role,” March 14th, “rehearsing my lines for the comedy movie I am shooting all next week,” March 13th, “memorizing my script,” March 11th. Apparently the sailor shorts she’s wearing in this pic on her first day on set , were a Heidi design: “I am wearing my sailor shorts I designed in the movie!!!,” she tweeted yesterday.

Meanwhile, Nicole Kidman landed in LA, March 15th with husband Keith Urban and daughter Sunday Rose — no doubt to prep for her role in the film. And listen, you have to hand it to Heidi — she doesn’t lack for ambition. This role may only be a cameo but she surely sees it as the first step on her way to bigger things.” My dream is to star in the remake of Splash directed by Ron Howard! Please help my wish come true by send all your loving energy! I love you,” she tweeted on March 9th.
