So True? So False? Is Brooke Mueller in Rehab With Demi Moore?!

Rumor has it that Charlie Sheen's ex is also undergoing treatment at Utah's Cirque Lodge, where Moore has been for a little over a week

We wouldn't call it a coincidence exactly, but this sure is a small world.

Demi Moore has been spending her days at Utah's Cirque Lodge, heading out to the high-price treatment center the week after a seizure-like attack landed her in the hospital.

And while Moore certainly is not alone as far as being one on a list of famous patients who have stayed at Cirque over the years, Radar is reporting that another paparazzi target is rehabbing there now, too—Brooke Mueller!

Charlie Sheen's ex has been in and out of in- and outpatient treatment over the last year. And there are only so many $30,000 programs out there. Suspend your disbelief, folks, because this story is...

So false! Sort of.

"Yet another example of an unnamed source trying to bring some excitement into their otherwise boring life by making up stories about a celebrity," Mueller's rep told E! News of the tabloid tale, though declining to comment on her exact whereabouts.

A separate insider says that Mueller is not currently in an inpatient program at Cirque. Another source says she is residing at a home near the treatment center and attends sessions daily on the grounds. The source adds that Mueller did begin as an inpatient there 10 weeks ago and still has at least a month of treatment left.

The divorced mother of twins has struggled with substance-abuse issues. In December, after deciding that an outpatient program in L.A. wasn't working for her, she checked into a "long-term inpatient treatment center."

Despite Mueller's troubles, she has retained primary custody of her and Sheen's sons, who are in the care of a nanny and their grandma and get to see their daddy during visits. The twins have been visiting Mueller in Utah since she relocated there.
