E! News has confirmed that, after about a year of dating, the recently divorced actor has become engaged to real estate investor and Brooke Mueller.

According to Us Weekly, Sheen popped the question on a Costa Rican beach with a $500,000 diamond ring--a no-brainer, one would think, for the highest paid sitcom star on television.

This will be the third trip down the aisle for Sheen. His first marriage, to Donna Peele, lasted about a year before their divorce in 1995. The Two and a Half Men star's split from Denise Richards became official in November and he and Mueller were first spotted stepping out romantically in June 2006, when Sheen's rep confirmed that the 29-year-old on his arm was his girlfriend.
