Actor Charlie Sheen says he wants to have children with his fiancee, adult-film star girlfriend Brett Rossi.

The 48-year-old, who already has daughter Cassandra with former girlfriend Paula Profitt, daughters Sam and Lola with second wife Denise Richards and twin sons Bob and Max, four with former spouse Brooke Mueller, is "open" to having kids with his 24-year-old fiancee, but not just yet, reports tmz.com.

He further said: "I'm having way too much fun with her right now. So much fun it should be illegal."

Sheen also said that Rossi has spent time with his sons and she loves them as much as they adore her.
