Los Angeles: Actor Ashton Kutcher is taking his 'Two and a Half Men' tag "All will be revealed" too seriously as he shocked chat host Ellen DeGeneres by going nude on live TV.

The 33-year-old's modesty is covered by computer pixilation, according to reports.

Talking about the ad for the sitcom, which features equally under dressed co-stars Jon Cryer and Angus Jones with the tagline, "All will be revealed", Kutcher said, "It's getting a lot of attention. So I just figured I'm going to do everything nude from now on." Before dropping his robe on the show.

When DeGeneres said, "I don't know if that's a good idea. Really." Kutcher joked, "Yeah. Whatever I'm doing I'm just going to do it nude. Let's do this."

The segment will be aired on September 12.
