The Deadpool star, 39, posed as an unprepared reporter, warning Jackman, “Some of these questions I may have written before I saw the movie,” before jumping into the impromptu chat.
“Do you do all your own acting?” Reynolds jokingly asked his X-Men costar.
"If they're sex scenes, I do them," Jackman replied, trying to keep a straight face. "It's the key to a good marriage."
"Do you ever age?" Reynolds then asked the 47-year-old Wolverine hunk.
“Not since 2008,” Jackman quipped, referring to when he was crowned Sexiest Man Alive.
Reynolds also poked fun at gorgeous wife Blake Lively by asking a fan question seemingly posed by her.
“A Blake Lively in New York City, New York … writes, 'Hugh, I tried calling you on the burner phone and you didn't answer. Are we still meeting at the Gansevoort Hotel this afternoon? I don't have much time because Ryan's having a mani-pedi from 3 to 4,” the funnyman read off the card before realizing, “I’m having a mani-pedi at 3 … that’s super weird.”
Eddie the Eagle tells the story of British ski jumper Eddie Edwards. Jackman portrays Edwards’ coach, Bronson Peary.
