Amanda Seyfried has made quite the claim about her former co-star and close friend Channing Tatum and their antics on the set of Dear John.

The two Hollywood stars played lovers in the movie adaption of the Nicholas Sparks book and over 10 years later the romance is still a fan favorite for many (if you need a good cry, that is).

While the film itself is extremely emotional, it seems that Seyfried and Tatum tried to keep things light on set and would constantly try and 'eff with each other'.

Speaking to Deadline about some of her favorite on-set memories, The Housemaid actress shared: "I don't know if it's my favorite but it's fun to talk about because it just goes to show the relationship that I had with Channing Tatum in Dear John.

"He and I effed with each other the entire movie in like a super, super fun way. He's very, very funny."

Seyfried continued to reveal a time when Tatum actually peed on her...

She recalled: "He peed on my leg once without me knowing. I didn't realize at first and then I was like, 'Oh that's why he's standing so close to me'.

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

Safe to say there was no method acting for Dear John then...

UNILAD has approached reps for Tatum for comment.

Despite his prank on her, in the years that followed Seyfried still hailed Tatum as one of her favorite co-stars.

"Channing and I have a very similar set behavior," told E! News in 2015. "We don’t take anything too seriously, but we’re shooting a movie that’s very heavy, all about love and romance. It’s a tear-jerker, so we just like to play around."

And Seyfried isn't the only one to have been subjected to Tatum's hijinx either as the actor's previously admitted to pranking Rachel McAdams on the set of The Vow.

"I did have a stunt pee pee that I had made for her for her reaction," Tatum told Entertainment Tonight in 2012 of the scene in which McAdams is surprised by her naked co-star walking into their bedroom.

"It was a little prank that I pulled on her. It's in the movie – her reaction was spot on. I didn't have a lot of faith in her reaction because it was cold that day, and I didn't want her to be laughing and pointing. I wanted her to be shocked."
