Sports Illustrated cover model Brooklyn Decker (pictured) has joined Columbia Pictures’ romantic comedy Just Go With It starring previously announced Adam Sandler and Jennifer Aniston.

Production is set to begin in Los Angeles in March in time for a Valentine’s Day 2011 release.

Sandler will play a man who recruits Aniston to pose as his soon to be divorced wife and pretends her children are his family. Decker will play a young girl who catches Sandler’s eye.

Allan Loeb, Tim Dowling, Tim Herlihy and Sandler co-wrote the screenplay and Dennis Dugan will direct.

Heather Parry brought the project to Sandler’s Happy Madison. Sam Dickerman and Adam Milano are overseeing for Columbia Pictures.

“We were thrilled when this movie came together with Sandler and Aniston who, in addition to their comic talents, have great chemistry together,” Columbia Pictures president Doug Belgrad said.

Decker is married to tennis star Andy Roddick and is represented by Gersh Agency, Impression Entertainment and Marilyn Agency for modeling.
