In Ice Age: Continental Drift, out in 2012, Lopez will play Shira, a snow leopard.

Also new to the franchise are Jeremy Renner, who will play a character named Gutt, Drake as Ethan, Wanda Sykes as Granny and Aziz Ansari as Walter.

But familiar faces will be back; Ray Romano as mammoth Manny, Queen Latifah as Ellie, Dennis Leary as Diego, John Leguizamo as Sid, Seann William Scott as Crash and Josh Peck as Eddie.

J. Lo's participation in the film falls under an overall deal she signed with Fox to be a judge on American Idol. But she also has her own projects in the works; see what big announcement is coming Thursday after the jump!
