Charlie Sheen is planning on making an honest woman out of Brett Rossi.
But as it turns out, she's already someone else's honest woman.
Rossi is still legally married to husband Jonathan Ross—though, as you might have guessed, that pesky little detail doesn't bother Sheen, who popped the question on Saturday.
"Charlie and Brett have absolutely no secrets between them," Sheen's publicist tells E! News. "Charlie is well aware that Brett has been separated for over two years from this man. Paperwork has been filed and it is going through the court system."
According to Radar Online, court documents show that Ross filed for divorce from Rossi last July, and she didn't file a response till Jan. 30, with Sheen family attorney Mark Gross acting as her lawyer.
A source told the site that nothing in particular was being contested and all should be resolved within the next few months.
Hours after getting engaged, Rossi told E! News all about Sheen's romantic proposal, which took her by surprise while they were vacationing in Hawaii.
"I was not expecting it at all," she gushed. "We had a beautiful Valentine's Day and he proposed to me early this morning after we watched the sun rise."
Furthermore, Rossi called the ring he gave her "classic and beautiful." (Pictures, please!)
Sheen kinda-sorta shared the news with one of his signature animated tweets.
Rossi is set to become the fourth Mrs. Charlie Sheen, while this will be at least the second trip down the aisle for her.
