Brooke Mueller has checked herself into rehab, TMZ.com reports.

According to TMZ, Mueller checked into The Canyon facility in Malibu on Feb. 9, the day after her husband Charlie Sheen was charged with felony menacing and misdemeanor assault for allegedly attacking her on Christmas Day in Aspen.

RadarOnline.com claims that Brooke is battling addiction to crack and alcohol. "Brooke has been in denial about her problem for a long time," a source says.

"Her mother has been attempting to convince her to go into rehab for a while now," the source adds.
