Which Washed-Up '90s Rapper Will Star Opposite Adam Sandler in I Hate You, Dad?

In case you haven't heard, Adam Sandler is busy casting his next film I Hate You, Dad, about "a father who moves in with his son and his fiancee, only to immediately start feuding with the bride-to-be." Sandler will play the father (obviously), Andy Samberg will play the son and Leighton Meester has just joined the cast as the troublesome fiancee. Sandler has also signed on a washed-up '90s rapper to play a large supporting role. Can you guess which one?

Vanilla Ice, of course! The rapper -- whose real name is Robert Van Winkle -- will join the cast as Antonio, a gay wedding coordinator from Long Island. This is probably not an April Fools' joke but maybe it should be one.

Additionally, proud Las Vegas Gangster Guide James Caan is also in talks to join the Happy Madison film as Meester's on-screen father.

I Hate You, Dad is scheduled for a June 15, 2012 release.
