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

Rossi, who Sheen calls Scotty, shared on her Twitter page a photo of herself with Sheen on vacation in Hawaii over the weekend and also said on Feb. 14: "Happy Valentine's day to the love of my life & my best friend! Everyday is Vday when I'm with you @charliesheen."

Sheen was previously married to Brooke Mueller and the two are parents to twin boys, Bob and Max. They divorced in 2011. Sheen also shares two daugters with ex-wife and actress Denise Richards. They were married from 2002 to 2006. The actor was also married to model Donna Peele from 1995 to 1996. Their marriage was annulled.
