Action star Bruce Willis "really doesn't care" about his looks and has said that he will never go for cosmetic surgery to retain his flamboyant appearance.

The Die Hard actor, whose ex-wife Demi Moore is rumoured to have spent thousands of dollars on improving her body, admits he doesn't indulge in a skin care routine and he would never consider going under the knife, Fox News reported.

"Cosmetic stuff, I am not a fan of it and I know a lot of people are. It's a big business and anytime you can make a lot of money off something it is going to stick around," Willis said.

"I don't plan on cutting myself up, you would be surprised, there are a lot of male actors that think about it just as much as women do. I don't think about it very often. I don't really care," the Golden Globe award-winning actor added.

The 54-year-old actor who tied the knot with model Emma Heming earlier this year, however insists that despite the growing he has been able to maintain his physique.

"I am surprised when I'm reminded of my age. I still feel like I'm about twenty four years old. I could still whoop a lot of guys if I have to," Willis said.
