Fox: 'LaBeouf had penis contest with Tyrese'

Megan Fox revealed that Shia LaBeouf and Tyrese Gibson once held a penis-measuring contest with each other.

Fox, who worked with the pair on Transformers, believes her former co-stars' on-set antics were a testament to their friendship and competitive nature.

Fox told OK! magazine: "Once on set, Shia and Tyrese were having a 'who has the biggest penis' contest.

"Then, who can put up the most weight on a bench press – Tyrese put up like 150, and little Shia put up 210, like, eight times or something. Tyrese was so ashamed of himself."

The 23 year-old actress also admitted that she enjoys working with LaBeouf and thinks the actor is very attractive.

"He probably is my favourite person in the entire world. Shia makes me laugh harder than anybody I’ve ever known in my life. I end up crying or almost peeing myself every time I’m with him. So he’s just my favourite – I love you, Shia! And he’s really super-handsome!"
