Hugh Jackman revealed that he forgot to warn his daughter about his nude scene in his latest movie, “X-Men: Days of Future Past,” which made him uncomfortable while watching the film with her, the 45-year-old actor told Daily News Wednesday.

“It is actually really cool to watch it with them until you get to the moment where you're naked onscreen and you forgot to warn your almost 9-year-old daughter," the actor reportedly said. "And she says, 'Dad, why aren't you wearing underwear?'"

The Wolverine star, who previously revealed that he would not be returning as the clawed hero after “Wolverine 3,” reportedly said that the strict diet that he had to follow on the day of the shoot for the nude scene was not a good idea as he was so thirsty that he passed out.

“You have no idea what goes into the lead up to a scene like that. It was a year ago,” Jackman told Daily News. “I know that exactly because it was May 21. I stopped drinking water for 24 hours, I pumped up on set for about an hour before shooting. And fell asleep by 2 o'clock!”

Jackman, who stars alongside James McAvoy, Nicholas Hoult, Michael Fassbender and Jennifer Lawrence in the superhero sequel, is currently busy promoting the movie. The Australian actor, who reportedly said that he feels that Wolverine fighting the Hulk would be an amazing scene to watch, also expressed his interest to see Wolverine join The Avengers.

"I would love to see him as part of The Avengers," Jackman reportedly said. "Because there's a great dysfunction among that team, and I think Wolverine would fit right into that.”
