Joe Gatto has been accused of behaving inappropriately toward one of his former employees … this just hours after denying sexual assault allegations that a different woman leveled against him.

People published a story Sunday … citing an anonymous woman who claims she worked for Gatto while he was on “Impractical Jokers” — and, she says he acted in a way that she describes as “sexual harassment.”

This woman says she first met Gatto when she was 15 … but, when she turned 18, his behavior toward her changed — becoming much more flirtatious.

Gatto would become frustrated when this woman refused to flirt back, she claims … and would allegedly treat her rudely if she rejected his advances.

Worth noting … People’s source does not provide any physical proof to back up her allegations, and Gatto denied any allegations of harassing behavior to People.

Like we told you … Gatto was accused of sexual assault by a user on TikTok in a now-deleted social media video that featured messages allegedly sent by the comedian.

Gatto denied all the claims to us in a statement … saying he’d “used poor judgment” in the past and has therefore “violated the trust of the people” he loves … but is confident anyone who knows him knows he “wouldn’t assault anyone.”
