Add Leighton Meester to the cast of Columbia's Adam Sandler-Andy Samberg comedy "I Hate You Dad." TheWrap has confirmed that the "Gossip Girl" has joined the cast.
On Thursday, TheWrap reported  that Oscar nominee James Caan is eyeing a role in the comedy.
The movie is about a disagreeable father, played by Sandler, who moves in with his son and the young man's fiancee just before the son is to get married. The father and fiancee immediately clash. Badly.
Samberg plays the son and Meester plays the fiancee.
Sean Anders and John Morris ("Mr. Popper's Penguins," "Hot Tub Time Machine") are directing.
David Caspe wrote the original script and the "State" team of David Wain and Ken Marino ("Wanderlust") rewrote.
Jack Giarraputo, Heather Parry and Adam Sandler are producing through their Happy Gilmore Productions.
Meester is repped by WME and Leverage Management.
Variety  originally reported the story.
