Anger Management star Charlie Sheen is set to walk down the aisle for the fourth time after popping the question to his partner Bret Rossi after "sunrise" yesterday (February 15).

Speaking to E! News about the proposal, the bride-to-be said: ''Yes! We are engaged! He even was a gentleman and got down on one knee. I was not expecting it at all.

''We had a beautiful Valentine's day and he proposed to me early this morning after we watched the sunrise . . . The ring is classic and beautiful, but I don't have any photos to share just yet.

''This is the happiest moment of both our lives. He's my best friend and my soulmate.''

Sheen was previously married to Donna Peele, between 1995 and 1996, Denise Richards who he married in 2002 and split from in 2006, and Brooke Mueller who was Charlie's wife from 2008 to 2011.
