Charlie Sheen is engaged.

His bride-to-be is Brooke Mueller, a real estate investor, Sheen's spokesman, Stan Rosenfield, said Thursday.

Rosenfield said Sheen, 41, proposed to Mueller, 29, during a recent trip to Costa Rica. He said the couple met in April 2006.

Sheen has two daughters, Sam, 3, and Lola, 2, from his marriage to Denise Richards. They divorced last year.

He stars in the CBS sitcom "Two and a Half Men." His screen credits include "Platoon" and the "Hot Shots!" movies.
