London: Pop diva and actress Jennifer Lopez is all set to lend her voice to the fourth 'Ice Age' movie, 'Continental Drift'.

The 41-year-old star will play Shira, a sabre-toothed tiger who melts the heart of Diego, the main protagonist, played by Denis Leary.

The cast also includes 'The Hurt Locker' star Jeremy Renner, who will portray the role of Gutt, a self-styled master of the high seas, an entertainment magazine said.

Also on board are Canadian hip-hop star Drake, comedians Aziz Ansari and Wanda Sykes, and Nickelodeon mainstay Keke Palmer. Returning to the Fox franchise are Ray Romano, Queen Latifah, Denis Leary, John Leguizamo, Seann William Scott and Josh Peck.

Romano returns as Manny and Queen Latifah as Ellie, both mammoths. It was not known what roles the other new arrivals would play.

The first three "Ice Age' films have grossed nearly USD 2 billion at the worldwide box office, putting Fox and production partner Blue Sky Studios squarely in the animation game.

'Ice Age' is becoming a year-round brand for Fox, what with a Christmas television special is being planned, along with a mobile game and online game. 'Continental Drift' hits the theaters on July 13 next year.
