Josh Hutcherson got "Hunger Games" co-star Jennifer Lawrence to unleash the waterworks - and crying had nothing to do with it.

While on the subject of on-set pranks during a roundtable discussion with Hutcherson regarding the upcoming new film, the actor admitted that at one point he pulled a particularly nasty gag on his fellow thesp, depositing a "life-size dummy" with a "mangled face" inside the bathroom of her trailer to freak her out. Unfortunately for poor Lawrence, the sight scared her so badly that, well...we'll let Josh tell it.

"She went to go to the bathroom and opened the door, and there was the dummy. And she apparently peed her pants," said Hutcherson. "I didn't see it, but yeah, sources say that she actually opened the floodgates...She could confirm it, I'm sure."

When it came Lawrence's turn to answer some questions, the unfortunate topic of her involuntary urination came up - and she understandably seemed a tad mortified that the incident had been making the press rounds at all.

"He's told everybody that," she said in embarrassment. "I thought it was like a one-time thing on 'Ellen'...and then it was like everywhere! [Laughs]...Yeah. So thanks, Josh."

So will she be getting him back while filming the sequel?

"Oh, yes. I mean, I [already] kicked him in the head and gave him a concussion," she said, referring to an accident that occurred during production of the first movie. "But there's still more."

"The Hunger Games" hits theaters on March 23.
