Hope springs eternal for Charlie Sheen: The "Anger Management" star is engaged, aiming to get married for the fourth time.
His lady of choice is Brett Rossi, a former porn actress, according to TMZ, which first had the news about the engagement.
The proposal, which reportedly found Sheen down on one knee, happened in Hawaii, where the actor had flown Rossi in a private jet.
"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 sun rise," Rossi, whose nickname is Scotti, told E! News on Saturday.
Sheen on Friday had exuberantly tweeted, "in a moment of Kray-zee gratitude; I got my gal!! 4evurr! but I also have this! xox c #LoveMyKids #TyB," along with a cute Valentine.
Previous Sheen marriages have included one to Donna Peele, which was annulled, the star pointed out in a quirky confirmation of the news to People. In it he referred to "three" being the charm. He was also married to actress Denise Richards, with whom he has two young girls, and Brooke Mueller, with whom he has twin boys. Sheen also has an adult daughter with his onetime high school girlfriend.
And though sources close to Sheen told TMZ that their pal is taking things very seriously this time, Radar Online reports that even though he believes Rossi to be his soul mate, he won't tie the knot without a prenup protecting his estimated $125-million bankroll. Sheen had a prenup with Mueller, but not with Richards, the site said.
[For the record, 3:33 p.m. Feb. 17, 2014: This post originally said this was Sheen's fourth engagement. Rather, this would be his fourth marriage. He has been engaged five times, including once to Kelly Preston, who ended their engagement before they walked down the aisle.]
