Coming clean! Colin Farrell and Vince Vaughn stopped by The Tonight Show on Thursday, June 18, and confessed some wild secrets. The two stars caught up with host Jimmy Fallon ahead of Sunday's Season 2 premiere of True Detective

"I'm here with Colin Farrell," Fallon, 40, began. "We're about to play a new game of deception — it's called True Confessions. We're gonna need another player to fill out the table. We have the man for the job. Please welcome Colin's costar from True Detective, Vince Vaughn."

Farrell, 39, welcomed Vaughn to the stage, getting hyped for the game. The Irish Total Recall star and the 45-year-old Internship inherited Matthew McConaughey and Woody Harrelson's lead roles, starring in the acclaimed HBO show with Rachel McAdams

"In front of each of us are two envelopes containing confessions," Fallon explained. "Some of the envelopes [have] something that actually happened to us in real life, and the second envelope is a lie. Once you read your confession, the other two players have 60 seconds to interrogate you and then they each have to guess whether you have been lying or telling the truth."

Farrell started things off, reading from his card, "When I was a late teen, I got brought in for questioning as a suspect in an attempted murder." 

Vaughn and Fallon spent their 60 seconds doing their best detective work, and finally guessed correctly that the confession was, in fact, true.

"I was supposed to bring my mother to the airport — I was in Sydney, Australia," Farrell spilled. "I was pulled in by the cops and they showed me a photo of the pencil sketch of the guy that had attempted to murder this other gentleman. [He'd] beat him up and left him in his own apartment and set the apartment on fire and split, thereby leaving the guy to burn to death. It was me. They said, 'What do you think about that picture?' And I went, 'I think I'm in trouble.'"

"It was terrifying," he continued. "I was there for about six hours. Thankfully, a friend of mine had kept a journal and that particular night at that particular time, we were at a party on the other side of town doing ecstasy."
