Charlie Sheen is engaged to his porn star girlfriend.
The actor had dated a string of adult performers in the past and is currently with blonde star Brett Rossi.
Sheen used the Valentine's Day weekend to pop the question.
It will be the 48-year-old's fourth marriage.
Sheen wed Donna Peele in 1995, but they divorced a year later.
In 2002 he married actress Denise Richards, who he has two children with, Sam and Lola.
Richards filed for divorce in 2005, after which Sheen began a relationship with Brooke Mueller.
They wed in 2008 and have twins Bob and Max together, but finalised their divorce in 2011, among a highly publicised custody war.
Rossi seems over the moon about the engagement and opened up about the proposal to E!.
"Yes! We are engaged! He even was a gentleman and got down on one knee," she said. "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.
"The ring is classic and beautiful, but I don't have any photos to share just yet. This is the happiest moment of both our lives. He's my best friend and my soulmate."
