Jennifer Aniston wasted no time moving on from the disappointing reception of her latest film, “The Bounty Hunter,” which was panned by critics as being “brainless.” Despite coming in third at the box office behind “Alice In Wonderland” and “Diary of a Wimpy Kid,” the actress has already started filming her next romantic comedy.

She was seen on set in Los Angeles alongside Adam Sandler and Brooklyn Decker, staying busy with back-to-back projects without missing a beat.

Jennifer Aniston wasted no time jumping into her next project, Just Go With It, right after finishing promotions for The Bounty Hunter. Alongside Adam Sandler and Brooklyn Decker, they began filming scenes outside the plush L’Hermitage hotel in Beverly Hills. The 41-year-old actress looked stunning in a classy cream dress, accessorized with a beige belt and matching strappy heels.

Originally named Pretend Wife, Just Go For It follows the story of a plastic surgeon (Sandler) who persuades a single mom (Aniston) to act as his soon-to-be-ex wife to win back the woman he loves. Decker, 22, who is happily married to tennis star Andy Roddick, will play Sandler’s love interest in the movie.

Enjoying a joke: The three actors filmed some scenes in front of the L’Hermitage hotel located in Beverly Hills. Nicole Kidman is also part of the movie, but her character details are being kept secret. Reality TV star Heidi Montag has a surprise cameo in the film, catching Aniston off guard. When questioned about Montag’s involvement by Access Hollywood, Aniston responded tactfully, saying, ‘I just found out about that… it’s interesting and entertaining.’

Puzzled by the plot of the movie? Us too! Adam Sandler portrays a plastic surgeon who persuades Jennifer Aniston, a single mother, to act as his pretend ex-wife in the upcoming film. Aniston praised Heidi Montag saying she is a great fit for the role, yet kept mum on the specifics of her character. Rumor has it that Montag, who just underwent 10 cosmetic procedures, will appear as one of Sandler’s patients. Keep an eye out for Just Go With It, set to hit theaters in February 2011.

Blazing white: The 41-year-old flaunted her amazing physique in a chic, form-fitting dress.
