Famed prankster Ryan Reynolds once gave a close friend's office a completely makeover, painting the room and everything in it an "ugly" shade of red.

The actor and known funnyman recalls his most elaborate joke in a new interview with Men's Health magazine, admitting he may have taken the prank a little too far.

"A friend of mine left town for a week. When he was gone, I painted his entire office puce," the Deadpool star shared, describing the "strange colour" as "this muddy, ugly sort of red".

"But we didn't just paint his office that colour - we painted everything in his entire office that colour," he continued, adding they painted "the inside of his desk, every pencil, every pen - everything".

Reynolds' wife Blake Lively is well aware of her husband's love of a good prank. He previously revealed he had jokingly played Marvin Gaye's classic Let's Get It On while the actress was giving birth to their first child, daughter James, in 2014 - and she wasn't happy about it.

"It was like steak knives came out of her eyes," he explained during a 2016 appearance on Late Night With Seth Meyers talk show. "She was like, 'Are you... kidding me right now?!'"

The couple, which wed in 2012, also shares little girl Ines, who turns one in September (17).
