Jake Gyllenhaal

It's fair to say that Jake Gyllenhaal has struggled to keep it in his pants and worried that his "protrusion" would change the tone on set.

Whilst shooting some intimate scenes with Jennifer Aniston for 'The Good Girl', Jake was left embarrassed after he became excited.

When pressed about how difficult filming those scenes with Jennifer were on Howard Stern's radio show, he confessed: "Oh yeah, it was torture. Yes it was, yes. But it was not torture. I mean, come on! It was a mix of both."
