Brooke MuellerJust a day after being released from a Los Angeles hospital after falling ill from pneumonia, Brooke Mueller has checked herself into rehab.

Mueller, who currently has a restraining order against husband Charlie Sheen after an alleged domestic violence incident, entered a treatment facility for drug and alcohol addiction in North Carolina, ETonline.com reports.

However, Mueller's lawyer claims she's just recovering from pneumonia, not in rehab, according to TMZ. But her stepfather says she is in a treatment center. "She is recognizing that she needs help and she can't do it on her own," he told RadarOnline.com.
