Charlie Sheen is claiming he has got married.

The 'Anger Management' star said Sunday he has married his porn star girlfriend, Brett Rossi, while on their current trip to Iceland.

Posting a picture of them together outside the former French consulate building in Reykjavík -- where a 1986 Cold War summit was held between then U.S. president Ronald Reagan and USSR leader Mikhail Gorbachev -- Sheen wrote on his Twitter page:

'S' is a nickname for Rossi, who also goes by the name Scottie.

Rossi would be Sheen’s fourth wife, after Donna Peele, Denise Richards and Brooke Mueller.

Earlier in the day, Sheen had paid another romantic tribute to Rossi, uploading a picture of her sniffing a rose, and writing: “jus wen ya thot the "idea" of a perfect rose was bred by an ordained magistracy of all things groovy SHE arrived. (sic)”

Sheen is also father to four children: Sam, nine, and Lola, eight, whom he had with Richards, and four-year-old twins Bob and Max, whom he had with Mueller.
