Charlie Sheen and Denise Richards will enter private mediation next week in a bid to resolve their child support issues.

The 'Anger Management' star, who has two daughters Sam, 10, and Lola, eight, with his ex-wife, wants his monthly $55,000 child support payment to Denise, 43, reduced and for her to be evicted from one of his houses.

A source told gossip website RadarOnline.com that the actor's lawyers have ''formally notified Denise and her lawyers that they will be headed to private mediation next week to try and get the child support reduced.

''The mediation will be handled by a retired judge who has handled various issues for the former couple over the years since their divorce. It looks like this will go down early next week. Wednesday by the latest.''

But the source added: ''Charlie could be taking a huge gamble by taking Denise to the mediator. There is a chance that the judge could actually increase the child support to Denise because of his lucrative 'Anger Management' deal with FX. This could be a can of worms Charlie might wish he never opened.''

Charlie, 48, and Denise were previously close friends but fell out in December, after he blasted her for not inviting him to spend Christmas with her and their daughters.

He allegedly wants his child support reduced because he claims he isn't allowed to spend anytime with the girls, even though Denise has sole custody.
