Following in his wayward daughter, Lindsay Lohan's footsteps, Michael Lohan has checked into Celebrity Rehab and isn’t being treated for an addiction, but for anger management issues, a show insider tells RadarOnline.com.

"Michael is absolutely 100% sober. He hasn't been using drugs or alcohol, but he is being treated for anger management issues. Michael has tremendous admiration for Dr. Drew, and was given this opportunity to better himself, and he took it," says the source.

Shooting began on Wednesday and Michael’s treatment is expected to last for about 21 days.

The show insider dishes, "Michael wants to deal with his anger issues in a controlled environment. He wants to be a positive role model for his children and he has a lot of unresolved feelings of anger towards Dina, and that needs to be dealt with. Producers of the show are hoping that Lindsay, Dina, and the other children would consider appearing on the show for family counseling, if they are comfortable in doing so. Dr. Drew wants to help heal this family and just get them sitting down in the same room, that would be the first step."
