London: Hollywood actor Hugh Jackman's son thinks he is embarrassing even though he portrays 'X-Men' hero Wolverine on the big screen.

The 42-year-old actor insists his son Oscar, 11, his eldest child with wife Deborra-Lee Furness, doesn't find him cool, stated a news report.

"I just did this one-man show in Toronto. There's an early song where I'm talking about how I like to dance but I'm Wolverine... it's a funny, fun thing. I was dancing and being a bit of a goofball. My son turned to my wife and said, 'My dad is so embarrassing'. He thinks I'm embarrassing," Jackman said.

The actor, who will portray the character of Wolverine for the sixth time in the series, said he finds it really hard to put on weight for the character.

"I'm just a tall, skinny guy that's had to put on weight for Wolverine, basically. The reason I had never really gone back to how my body would be is because Wolverine has been every three years and I know how hard it is to put on the weight," he added.
