The 24-year-old daughter of Ozzy and Sharon Osbourne is reported to have checked into an unnamed center in Los Angeles for 30 days.
Her reps say in a statement to PEOPLE, "Kelly Osbourne has voluntarily entered a medical facility to address some personal issues. Her family stands by and supports her."
No further details were provided.
Late Thursday, Osbourne's mother Sharon was quoted on RadarOnline.com as saying, "Yeah, Kelly's in rehab. What else can we say? She knew that it was the right thing to do at this point and we're proud that she did it. The family is all standing behind her. Kelly knew that she needed help and she's getting it."
The matriarch added, "We just pray that everything's going to be okay."
Previous TreatmentNearly five years ago, at the time of her family's reality series The Osbournes, Kelly Osbourne checked into a treatment facility in order to deal with a painkiller addiction.
During an interview with PEOPLE in August 2008, Osbourne addressed her relationship with alcohol and what she got out of her stay in rehab. "I'm not going to say I'm clean living, because I still drink and I've definitely had my moments," she said. "It's not just moderation, it's knowing limitations on everything."
Of treatment, she added, "Rehab teaches you the skills to change your life, but it's up to you to do so."
This week, on Monday it was reported that Osbourne had been arrested for allegedly slapping a gossip columnist last summer. She is scheduled to return to see authorities in March.
