Kelly Osbourne has entered a rehabilitation center and will stay for 30 days, her mother Sharon confirmed.

The 24-year-old singer/DJ and daughter of rocker Ozzy Osbourne has been checked into an unnamed center in Los Angeles, according to People.

Kelly Osbourne has voluntarily entered a medical facility to address some personal issues. Her family stands by and supports her, her reps said in a statement.

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, her mother Sharon Osbourne told RadarOnline.com.

Kelly knew that she needed help and she's getting it... We just pray that everything's going to be okay, she added.

In April 2004, Osbourne entered treatment in Malibu after admitting to family that she was addicted to painkillers.

Earlier this week, Kelly was arrested for allegedly slapping a journalist in a London nightclub last summer.
