Sheen also tweeted this message:
Rossi confirmed the news to E!, telling a more conventional story. "Yes! We are engaged! He even was a gentleman and got down on one knee. 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.
She added, "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."
This will be the fourth marriage for Sheen, whose brief first marriage, to Donna Peele, ended in an annulment. He divorced both Denise Richards and Brooke Mueller.
