Jonah credits Dustin with helping him get his big break into movies, after Dustin lined up his first film role in I Heart Huckabees.

He has been friends with Dustin's family since childhood.

Now he and Dustin's youngest daughter Ali, 24, have decided to take things up a notch.

"[Ali and Jonah] were friends when they were growing up. Jonah is good friends with Ali's brother, Jake," a source told the New York Post. "Dustin discovered Jonah when they were in high school."

The Superbad star is said to have spent the Christmas period with the Hoffman family. Jonah enjoyed sun, sea and sand while spending time with Ali.

"Jonah was in Hawaii over the holidays with the Hoffman clan," the source added.

The actor celebrated his 28th birthday last month. Brad Pitt, Angelina Jolie and Zooey Deschanel all attended the party and had a drink with their friend.

Jonah was spotted dancing with several different girls throughout the evening.
