It's nice to hear that the ex-couple can still hang out together after divorcing in 2010, but this is just ridicules!

Despite the fact that Brooke Mueller is on probation for her drug arrest in Aspen, last December, the mother of two has relapsed and has checked back into rehab to treat her addiction to crack cocaine.

What's even more shocking, a four day bender with ex-hubby Charlie Sheen was to blame for sending the mother of the pair's three-year-old twins back to rehab.

According to reports, Brooke met up with her ex and partied for four days straight at his Mulholland Estate, which spiraled her back into relapse.

Mueller's rep Steve Honig confirmed that his client was seeking treatment, saying in a statement:

    "As Brooke told the Court a couple of weeks ago, she will spend the rest of her life trying to stay sober, with every day being a struggle. As part of her ongoing treatment and as planned, she voluntarily checked herself into a rehab facility several weeks ago. Brooke is doing well and is grateful she has a strong support system on which she can rely."


Because of checking herself back into rehab, she was unable to spend Mother's Day with sons Max and Bob, on May 13. Will Brooke be sent to jail for violating her probation?
