Lindsay Lohan will be spending the upcoming Christmas holiday in Southern California, RadarOnline.com has learned exclusively, though it's still unclear who she'll be surrounded by.

Her mother Dina “wants Lindsay to go home to Long Island for Christmas, [but] that won't be happening," a source with knowledge of the situation told us. "Judge Elden Fox was very clear with his order that he wanted her to stay in rehab until after New Year's.”

Brooke Mueller has voluntarily checked herself into a sober living facility, RadarOnline.com has confirmed.

The soon-to-be ex-Mrs. Charlie Sheen "felt weak and that she was struggling and wanted to get counseling to build up her confidence and strength again. Her sobriety is the utmost importance to her," a source tells RadarOnline.com exclusively.

Brooke is spending only nights at the facility, a family insider tells us. "Brooke is going to be spending the days with her boys. She will have a sober living companion with her.  She'll go to the sober living facility at night.  The hardest part for her is not tucking her boys in when they go to bed."

Little Bob and Max Sheen will have their grandmother to handle that job.  Brooke's mother Moira Fiore is staying at her daughter's Los Angeles home and is taking care of the twins.

It's been a rough year for Brooke, who has battled addiction most of her adult life.

"Brooke has been dealing with so much. From raising her twin sons, dealing with the aftermath of her Christmas Day incident with Charlie, and then nearly dying of pneumonia several months later," the family insider says.

In recent weeks though, Brooke had been enthusiastic about the direction her life was taking.  She was "clean and sober," another insider told us, and excited about the new reality show she was set to film with Paris Hilton.

The show, for the Oxygen network is built around Paris' jet set life and features her three closest friends, including Brooke.  The twosome shot several scenes together in recent days.

But the upcoming Christmas holiday and the reality of the year she was ending began to overwhelm Brooke.

"She wants to put 2010 behind her. Brooke used to love Christmas, but because of what happened last year with Charlie, she began to get very, very depressed recently. Even though it's a year later, Brooke is still dealing with the emotional scars of it," a family insider tells us.

"The fact that Brooke recognized she was beginning a downward spiral, and wanted to stop it before it got out of control, is a very positive step for her. Brooke wants to be the best mom possible for Bob and Max. Being the best mother possible to them is what her motivation is."

The event will feature speakers, health and spiritual activities, food, entertainment and a raffle.

Located on the grounds of an estate once owned by Elizabeth Taylor at the top of Benedict Canyon, the center devotes itself to educating and saving the lives of those battling substance abuse.

Lindsay Lohan may be trying to put off jail time by checking into a sober living facility, but it’s not good enough for her dad, Michael.

In an exclusive interview with RadarOnline.com, Michael Lohan says his daughter needs to GET sober before she lives sober.

“I’m happy that she’s taking positive steps, but a sober house is NOT a rehab and it does not detox someone off prescription drugs,” Lohan told RadarOnline.com. “It [a sober house] serves no purpose other than staying clean off non-prescription drugs and alcohol. In Lindsay’s case, the prescription drugs ARE the problem.”
