Ashton Kutcher

Ashton Kutcher is wasting no time in showing Charlie Sheen is out and he's the new center of attention on Two and a Half Men.

The actor makes his Men debut on Monday, Sept. 19 at 9/8c and takes center stage in the new opening credits as he, Jon Cryer and Angus T. Jones, who once held that coveted center spot, sing their opening "manly men" song.
