Lindsay Lohan -- 'Worried' About Charlie Sheen

Lindsay Lohan believes Charlie Sheen is in the midst of a "life or death situation" ... and has told friends she's "thrilled" that he's checked himself into a rehab center.

Sources close to Lohan tell us ... Lindsay is "worried" about Sheen because his most recent bender shows "obvious signs of addiction" ... something Lindsay knows about all too well.

But after Sheen decided to check himself into a treatment center Friday afternoon, Lohan is confident he can get his life back together ... if he commits himself to sobriety.

We're told Lindsay "understands the problem of having the wrong people around and wants Charlie to understand that he needs to surround himself with positive, sober people."

Lindsay Lohan: “I Did NOT Leave” Rehab.. Yet

Earlier today, Radar Online reported that Lindsay Lohan had left the Betty Ford Center, but the site was wrong.

In an exclusive statement , Lohan told Gossip Cop, “I didn’t leave [rehab],” adding “[I'm] going to the gym.”

She also corrected the rumor that she’s permanently moving out of her L.A pad. “I’m not moving from my apartment… That’s not true either.”

TMZ also posted earlier today that Lohan was going to stay at Betty Ford until this Saturday, but Gossip Cop is told by a source close to the actress that she’ll probably leave the center sometime within the next 24 hours.

Lindsay Lohan To Live With Dina Post-Rehab

Lindsay Lohan will not head back to her West Hollywood condo when she leaves the Betty Ford Center on January 4th after her court-ordered stay at the treatment center. Instead, the troubled starlet will travel to a secret location where she will stay with family, mom Dina, and her siblings, after she exits rehab next week.

A source close to Lindsay tells X17online exclusively:

"Lindsay will be staying at a (secret for now) location starting the 4th of January, with her family, mother and siblings. She also has the support of me and her other friends. As long as she doesn't fail any tests (and everyone is going to make sure she doesn't) she'll be put on summary (unsupervised) probation on February 25th."

Is mom Dina really the best guardian to protect Lindsay's sobriety? She's been known to hit up clubs with both her girls -- even with underage Ali.

Our source tells us:

"She [Lindsay] got to see her family on Christmas, and is of course be staying at a new (secret for now) Betty Ford sober living house with out the cameras on her. From our conversations I'd say she's very lucid and clear minded."

Is Lindsay on the right track or the road to nowhere with her post-rehab plan?

Demi Lovato's Rehab Christmas With Her Family

As Demi Lovato continues to receive profession treatment for "emotional and physical issues," the Disney star had just one Christmas wish this year: to ring in the holiday with her family outside of the center.

Lovato, 18, was allowed to leave the treatment facility for the day on Christmas, a source close to her family tells PEOPLE. She returned later in the evening after celebrating with her mom, step dad and two sisters.

"It is the most important holiday to her," the source says.

Lovato checked into the treatment center late October after a fight with a dancer, Alex Welch, on the Jonas Brothers World Tour. What was described as a "short, physical altercation" was settled in time for Christmas, and Welch told PEOPLE she is "ready to move on."

Although there is no date set for the completion of her treatment, a source close to the family told PEOPLE in November that "Demi knows she needs the help and knows that she is where she needs to be right now."

Alexis Neiers Sent to Rehab After Heroin Bust

They didn't name the show Pretty Wild for nothing.

E! reality star Alexis Neiers, 19, was ordered to spend a year in residential rehab Thursday after her December 1 arrest for possession of black tar heroin as well as a fake I.D.

Neiers, who has been in jail since the arrest, was released from Century Regional Detention Facility in Lynwood, Calif. in July after serving 30 days of a 180-day sentence she received after pleading no contest to felony burglary in connection with a break-in at actor Orlando Bloom's home.

The reality star, whose mother Andrea Arlington and little sis Gabrielle were in court to support her, will report to Malibu's SOBA Recover Center.

And though Neiers avoided a possible two-year prison sentence, she didn't escape a stern warning from Judge Peter Espinoza.

"Let me make this clear. If you come back to me for using heroin you are going to prison," Espinoza said. "No one is going to do anything to change the fact that you are a heroin addict for the rest of your life. They can only help you stop using."
