Michelle Trachtenberg: Zac Efron's My Daddy

Gossip Girl‘s Michelle Trachtenberg is wanting to wear a t-shirt to the premiere of her upcoming movie, 17 Again, that reads ‘Zac Efron‘s My Daddy’, reports US Magazine.

The 23-year-old starlet spilled to the magazine at a recent event that she has the urge to wear the garment but then claims that Zac‘s girlfriend Vanessa Hudgens probably wouldn’t like it too much. She also shared that the idea of Zac, 21, being her father is “hysterical.”

17 Again is the story about a guy, Mike O’Donnell (played by Zac Efron and Matthew Perry), whose life didn’t quite turn out how he wanted it to and wishes he could go back to high school and change it. Michelle plays the role of the daughter, Maggie O’Donnell.

The film is set to hit theaters in April 2009. Check out the trailer below!
