Jennifer Garner was the "leader of the streakers" when she was at college.
The 42-year-old actress – who has children Violet, eight, Seraphina, five, and Samuel, two, with husband Ben Affleck – insists she was never a "party girl" but was always happy to strip off in front of her pals.
She told talk show host Conan O’Brien: "When I was in college, every summer I would work for free at a theatre.
"I didn’t drink. I was never a big party girl, but I streaked. I was just in a ‘naked frame of mind’ …I might have been the leader of the streakers and we just all streaked all summer."
Meanwhile, the former ‘Alias’ star also revealed she recently "rented" 120 goats to help clear rat-infested ivy from her home.
She explained: "Down the sides of the hill, we have this ivy… We realised that there were rats living in the ivy,.
"It started to feel like we needed to deal with this but it was expensive to tear out. And my husband was going on location and I told him, ‘Just go, I’ll take care of it.’
"I rented a herd of goats and I sent that picture to Ben on location. It was his first day on the ‘Batman’ set and I said, ‘Honey! I’m taking care of the ivy!’ That’s 120 goats. We had a party and we called it the ‘running of the goats’ and we herded them from the driveway to the ivy."
Sadly for Jennifer, she admitted the ivy grew back afterwards.
