The mother of Brooke Mueller has confirmed that her child is still battling with substance abuse problems.

In fact, Moira Fiore says Mueller has checked herself into a sober living facility for about the next two weeks.

"She is struggling with her sobriety and we are going away on a cruise so we feel better that she will be there while we are gone," says Fiore. "It is a facility for very wealthy people trying to fight addictions. Brooke is really trying to get her life back."

Unfortunately, it doesn't sound as though Brooke is as happy and healthy as she previously claimed.

But there is this piece of good news, courtesy of Kathy Hilton, who is shooting an Oxygen reality show with Mueller and daughter Paris Hilton: "Brooke is fine and taking preventative measures. [It] won't affect the show."

Thank goodness. We can all breathe easier now.
