WATCH: Jennifer Garner missed George Clooney's wedding… because of head lice?!

This is officially the most bizarre reason to miss a star-studded wedding.

Jennifer Garner has revealed the real reason she wasn’t slamming tequila shots at George Clooney's Italian wedding last weekend… and it involves an army of head lice taking over the Garner/Affleck clan.

Watch as Jen recounts her gross battle with the bugs on The Tonight Show with Jimmy Fallon … but be warned, it's bound to make you itch.

Okay, so she may be joking about the whole thing, recalling her first scratchy, smelly encounter with Mr Clooney. But it's much more interesting than hubby Ben's boring excuse about promoting his new flick Gone Girl.

Jen, you may have missed out on George and Amal's four-day nuptials in seven-star Venezian hotel, but at least you win our coolest celeb mum award.

Jen – 1, Lice – 0.
