London - Charlie Sheen's new fiancée wants to get pregnant as soon as possible.

Brett Rossi wants them to start their own family immediately but the 'Anger Management' star is reportedly reluctant, as he already has five children from previous relationships and a seven-month-old granddaughter, Luna.

A source told gossip website RadarOnline.com: "Bret wants to start a family with Charlie immediately. She doesn't want to wait to have kids, and thinks Charlie will be an amazing father."

The insider said that the 48-year-old actor "isn't quite ready to become a father for the sixth time. He definitely wants kids with Brett, but he doesn't want to rush into it. This is the one thing they can't seem to agree on!"

Charlie proposed to Brett on Valentine's Day on February 14, after less than four months of dating.

The former 'Two and a Half Men' star has 29-year-old daughter, Cassandra, with former girlfriend Paula Profit, daughters Sam, nine, and Lola, eight, with second wife Denise Richards and twin sons Bob and Max, four, with former spouse Brooke Mueller, and previously said he was "open" to having kids with his 24-year-old fiancée.

But he added: "I'm having way too much fun with her right now. So much fun it should be illegal."

The former porn star is still legally married to her first husband Jonathan Ross, who filed for divorce from her last July. - Bang Showbiz
