The pair, affectionately referred to by fans as "Taylor Squared," dated for a few months in late 2009. They even played a couple and shared an on-screen kiss in the Garry Marshall rom-com Valentine's Day, released in February 2010, two months after splitting up.
Lautner and Stamos, who recently signed on to star in the second season of Scream Queens, also opened up about joining the hit Fox horror comedy, and Lautner revealed that he actually talked his way out of being shirtless on screen.
"The first script had both of us shirtless in separate scenes," Stamos explained. "He talked his way out of it. It got rewritten."
"I've had so much shirtless in my life that I need a little break," Lautner said, eluding to his frequent appearances sans shirt in the Twilight franchise. "But there is a fair amount of sexy scenes for everyone. I haven't been shirtless yet but I've been stripped down a little bit."
As for Stamos, his shirtless scenes were re-written as well, but with the opposite result.
"Mine went from shirtless to completely naked in the shower," Stamos revealed. "Then, the next episode, it was already written. Glen Powell and I have a naked shower scene together."
"On Friday night I get a letter from my lawyer saying, 'Hey, check this out,' and it was from legal saying, 'We'd like to show John Stamos' butt in episode 203 and 202. Is that alright?' I was like alright, well, here we go," he continued. "I'm 53 next week, I might as well get it out there now."
While Stamos was ready to go au naturel, he did have an idea for a butt double.
"I'd use Taylor's," he joked. "Not that I've seen it, but I bet it's a good butt."
"Our first shot yesterday we came out of the elevator, they start on our shoes and they pan up," he recounted "Then [executive producer] Brad [Falchuk] goes 'John, could you grab yourself?' I’m grabbing myself. I felt like a piece of meat day one!" Check out the video below to hear more.
