Liam Neeson prank called Maggie Grace’s ex-boyfriend and told him to “..get your s–t together.”

In Thursday interview on “Conan,” Maggie Grace revealed that her onscreen dad, Liam Neeson, assisted her when she was a “hot mess” after a breakup. So Neeson took his “Taken” character into action and called Grace’s former boyfriend.

“This is Brian Mills. We’ve never met, and if you play cards right, we never will.”

“Now listen (bleeped out expletive). You’re lower than the pond scum so I’m just going to say this once.”

“You’ve made two mistakes: Your first mistake was dating out of your league. Your second mistake, well, let’s just say any more mistakes and I’ll break your other arm – slowly.”

“I don’t need to say it, but I have a particular set of skills.”

“And I don’t want to waste them on you. Now get your s–t together.”
