Mollen posed for a selfie as the naked American Pie star squatted on a toilet behind her, a magazine covering his genitals.

But Biggs' manhood wasn't completely out of sight in the Instagram picture - Mollen's quirky shot captured his genitals hanging beneath the mag.

Fans mused whether the big reveal was intentional until Mollen pulled the picture from social media, suggesting she didn't spot her man's testicles at first.
