Actor Charlie Sheen and his ex-wife Denise Richards will enter private mediation next week to attempt resolving issues related to their child support.

The "Anger Management" star, who has two daughters Sam, 10, and Lola, eight, with Richards, wants his monthly $55,000 child support payment to her reduced. Additionally, he wants her to be ousted from one of his houses.

According to a source, 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", reports RadarOnline.com.

"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," the source added.

It could be tricky.

"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," said the source.

Sheen, 48, and Richards were earlier close friends, but they fell out in December 2013 after he blasted her for not inviting him to spend Christmas with her and their daughters.
