Jodie Sweetin clapped back at a fan who claimed she had a sexual relationship with "Full House" co-star John Stamos.
Sweetin, who is 19 years Stamos' junior, responded to a fan who commented on a throwback Instagram photo she posted Sunday. The snap showed the actress and Stamos back when they were "babies" and was intended as a happy birthday post for the 55 year old.

A user commented on the photo and asked, "How can you still say uncle to him when it's been reported that you slept with him?! That's just nasty."
Sweetin, 36, shut down the troll, and made it clear the claim was categorically untrue.
"Hahahah...um...what?!" she wrote in the comment. "Yeah...that's def not true.”
