Idolator

From a just-spawned press release:

AEROSMITH frontman STEVEN TYLER will mark his return to television Monday, September 25 (9PM ET/PT) where he'll play himself on CBS-TV's Emmy-nominated prime-time comedy series "Two And A Half Men," starring Charlie Sheen and Jon Cryer. In the role, STEVEN appears as Charlie's famous Malibu neighbor, playing loud music and causing problems for Charlie. This is the second time TYLER will appear on the show, having done a voice-over as himself in 2003.

It's not hard to see why Sheen wanted to work with Tyler in person this time; thanks to all that tweaking and fixing, the Aerosmith singer is looking more and more like a 16-year-old girl every day.
