Charlie Sheen, Brooke Mueller Engaged

After more than a year of dating, Charlie Sheen and his girlfriend, Brooke Mueller, are officially engaged, People reports this morning.

Charlie Sheen, 41, first went public with Brooke Mueller, 29, a real estate investor, at the Chrysalis Butterfly Ball in Los Angeles in June 2006.

Brooke Mueller is the daughter of Palm Beach socialite Moira Fiore, and has been seen with Sheen, his children and even his ex-wife for over a year.

The couple's engagement was first reported by Extra and was confirmed by a Sheen family friend. According to Extra, Sheen proposed on a beach with a $500,000 ring.

Sheen became free to wed last November when his marital status to Denise Richards legally ended. The pair have two daughters, Lola, 2, and Sam, 3.

Denise Richards, 36, has extended an olive branch to Mueller and the women have been spotted together on more than one occasion.

"Denise wants her to feel comfortable," a friend of Denise Richards' said. "She put together a bag with toys for her and the girls (Lola and Sam) along with a card telling her she's glad (Brooke) makes their father so happy."

In fact, last night, People reports that Denise Richards publicly extended her best wishes to Charlie Sheen and his engagement to girlfriend Brooke Mueller.

As dysfunctional as their marriage was in its prime, Sheen and Richards have really done a commendable job of remaining amicable towards each other in the year since they separated. It's a lesson many celebrities can learn.

Not that they have to abide by it, of course. In fact, if Britney Spears suddenly started acting mature, what the hell would we write about?
