Brooke Mueller and Charlie Sheen

Charlie Sheen has invited his ex-wife Brooke Mueller to his wedding.

The 'Anger Management' star wants the 36-year-old actress, with whom he has five-year-old twins Max and Bob, to watch him tie the knot with his fiancée Brett Rossi.

A source told RadarOnline.com: "They all get along and are one big happy family. It might be unconventional for most people, but not for Charlie's wacky world!

"Having Brooke at the wedding will also show the twins that they all get along."

Charlie, 48, and Brett, are keen for Max and Bob to have a role in their big day and are planning on giving them "special gifts" to help them fit in to their new family.

The source explained: "The twins are going to be a part of the wedding ceremony. Charlie and Brett are planning on giving them special gifts to make Bob and Max feel a part of their new family."

Brooke, who has been to rehab for cocaine addiction more than 20 times, is reportedly "ecstatic" her former lover is marrying the porn star because they get on really well.

A source said previously: "She is so happy. Brooke has repeatedly been over to Charlie's house with their sons, Bob and Max, and she and Rossi have truly hit it off."

Charlie proposed to his 24-year-old girlfriend during a trip to Hawaii in February, but their wedding is currently on hold because she is yet to finalise her divorce from her first husband, Jonathan Ross.

Charlie also has a grown-up daughter Cassandra from a previous relationship and daughters Sam, 10, and Lola, eight, with his ex-wife Denise Richards.
