Ashton Kutcher is officially part of the Two and a Half Men crew.  At the CBS upfronts presentation (where CBS announces it's fall shows for ad buyers) on Wednesday Ashton was introduced as part of the cast for the first time.

Kutcher told the crowd "You'd almost think I won the lotto ... which I kinda did. I got the best job in showbiz, and I'm excited. ... I'm surrounded by the best, and I will work my a** off.""

Ashton of course replaces Charlie Sheen who went a little bonkers, to say the least, and then reportedly tried to get back on the show.  No go buddy, Ashton seems fired up to rock this one.
