Joyce is making it rain!
In this hysterical clip from Tuesday night's all-new episode of Just Jillian, Jillian Michaels surprises Heidi's mom with a stack of singles and a squad of male strippers for her 70th birthday celebration with all her friends!
Unfortunately, Jillian is only one of a few guests who seem to enjoy the party crashers and their raunchy lap dances.
"The stripper thing didn't quite go off as I anticipated," Jillian admits. "Grandma Joyce looked at me and said, 'I'm going to kill you, Jill.'" LOL!
Watch the entire hilarious clip above!
