Charlie Sheen just got engaged for the fourth time the day after Valentine's. This time his future partner in matrimony will be adult film star Brett Rossi, as he proposed to her this Saturday while the two were sharing a romantic getaway in Hawaii.

Brett shared the information with E! Online, "Yes! We are engaged! He even was a gentleman and got down on one knee. I was not expecting at all. We had a beautiful Valentine's day and he proposed to me early this morning after we watched the sun rise."

The couple began tweeting early that day with a message from Rossi to Sheen saying: "Happy Valentine's day to the love of my life & my best friend! Everyday is Vday when I'm with you @charliesheen." This was followed by a picture of roses and an uploaded photo of the two on their Hawaiian vacation

The 48-year-old actor responded with: "in a moment of Kray-zee gratitude; I got my gal!! 4evurr! but I also have this! Xox" Indicating a link to a large candid photo of his two sons.

Rossi is currently 24, which is 24 years a junior to Sheen. The three previous wives of Sheen included Donna Peele, from 1995-1996 and Denise Richards from 2002-2006. His most recent wife was Brooke Mueller, to whom he was married for three years from 2008-2011.

There has been no official photo of the ring Sheen proposed with, but she reportedly told E! Online that the ring was 'classic,' adding, "This is the happiest moment of both of our lives. He's my best friend and soulmate."
