Actress says Channing Tatum once 'peed on' her leg as a practical joke!

Okay, this is taking friendship to a whole other level.

Amanda Seyfried says Channing Tatum once "peed on" her leg and she now thinks it's hilarious.

Call me old-fashioned, but I have a strict "don't pee on my leg" policy with friends and family.

So, how did this prank even happen?

Seyfried told Deadline it went down while shooting the 2010 movie "Dear John" with Tatum.

She revealed the shoot with Tatum was full of laughs and recalled one particular prank on a beach initially filled her with horror.

"He and I effed with each other the entire movie in a super, super fun way. He’s very, very funny, and we had a great time," Seyfried shared.

"The Housemaid" star then confessed, "He peed on my leg once, without me knowing. He peed on my leg on the beach, and I didn’t realize at first, and then I was like 'Oh, that’s why he’s standing so close to me.'"

She added, "There was a coffee cup very close by, and a little bit got in the coffee cup, and he ran away as I was screaming. One of the make-up artists picked it up and was about to drink it, and I saved her."

Despite having a great time with Seyfried on set, Tatum revealed on an episode of "Hot Ones" how he really felt about the movie: “[It was] such a generic romance.”

He also admitted actors often have to "make bad things" to pay the bills.
