Jon Cryer looked like he had the time of his life early Monday (Sep 19) as he attended the presentation ceremony for the introduction of his brand new star on the Hollywood Walk of Fame. (We guess that’s a pretty good reason to look like you’re having the time of your life.)

Also spotted at the ceremony was Cryer’s “Two and a Half Men” co-stars Angus T. Jones, Ashton Kutcher, Holland Taylor and Conchata Ferrell (Berta), as well as the show’s creator Chuck Lorre and Cryer’s wife Lisa Joyner. Charlie Sheen was obviously not invited. (And even if he was, we doubt he’d even show up. Waaaaay too awkward!)

Later that night, nearly 30 million people watched when the 9th season of “Two and a Half Men” premiered.

Part 2 of the episode, which introduces Ashton Kutcher as Charlie Sheen’s replacement, will air next Monday evening (Sep 26) at 9 PM on CBS.
