Charlie Sheen hasn't had too much luck with his previous marriages. But perhaps the fourth time will be the charm?

The 48-year-old Anger Management star has been dating 24-year-old adult film star Brett Rossi, with whom he recently went on vacation to Iceland. He has previously been married three times and has five children.

Has Charlie made things official with Brett? On January 5, Charlie tweeted that he and Brett  whom he refers to as "S" because her nickname is Scottie  tied the knot during their trip.

"This is the house ware M. Gorbachev, R. Reagan did some epic," Charlie writes. "It's also where S and I GOT MARRIED! c #RumorMilUhPede."

But is Charlie being serious about being a newlywed? It seems not, as his rep tells Us Weekly, "He's kidding around." And when Brett was told about Charlie's tweet, she responded on Twitter, "hahahahahahahahahahahahahaha epic."

Charlie married Donna Peele in 1995 before they split up the following year. He has two daughters from his marriage to actress Denise Richards, from whom he finalized his divorce in 2006. Charlie and Brooke Mueller — with whom he has a pair of twins  ended things in 2011. What's one more try, right?

So is Charlie still single, or is he indeed off the market? Either way, we're sure that he's winning.
