Joshua Jackson and Eric Mabius "blushed scarlet red" when they bumped into each other "years" after their steamy gay sex scene in Cruel Intentions.

The 47-year-old actor's alter ego Blaine Tuttle got school footballer Greg McConnell (Eric) in bed and gave him a "b******" as part of a blackmailing scheme with Blaine's friend Sebastian Valmont (Ryan Phillippe) to convince Greg that Sebastian is a good guy and that Sebastian can win his bet with step-sister Kathryn Merteuil (Sarah Michelle Gellar) - to seduce Annette Hargrove (Reese Witherspoon) before the start of the school term.

Years after the "stressful" scene in the 1999 romantic-thriller film, Eric and his ex-wife Ivy Sherman happened to walk past Joshua whilst he took out his trash, and after a brief chat, Ivy asked how the pair are connected - which turned them red-faced.

In an interview with Men's Health magazine, Joshua said: "So then years pass - and I don't see Eric after a long time after we've had this experience together - and I'm taking out my trash one day, and he and his wife walk by, because they've just moved in down the street.

"She sees us see each other and have this moment of like, 'Hey, what's up?' And she's like, 'Oh, how do you guys know each other?'

"And the two of us, now well into our 30s, I think both blushed scarlet red. Like, how do you explain what that connection was?"

Cruel Intentions' director Roger Kumble got Joshua to perform the sexual act on his first day on the job.

Joshua recalled: "I wasn't on Cruel Intentions very much, but I do believe that my first day on this movie was giving a man head.

"And that can be stressful for a 19-year old heterosexual boy, to sit in a room, and give another man a b******."

Joshua got through it by committing himself to the acting job.

He added: "My stress test on this was to commit myself to this job that I had taken on and really make sure that I was all in, so to speak."
