Brooke Mueller Caught On Tape Smoking Crack Cocaine, Bargaining For Meth In Shocking New VIDEO

A shocking video of Charlie Sheen's ex-wife Brooke Mueller has now surfaced online.  The footage is of Mueller smoking crack and buying drugs, most likely meth.

The video shows the 36-year-old mother of twin boys desperately bargaining in a meth deal while smoking what appears to be crack cocaine out of a glass pipe.

The  video, which is undated, shows Mueller in a bathrobe looking glassy-eyed...and smoking from glass, and wanting "crystal" in a hotel room.

Where is the crystal? I am giving you $1500," Mueller says in the video.

Radar Online first uncovered the shocking clip. An insider who was present said it wasn't an exceptional night-just one of many.

The tipster said, "Brooke loved getting high. This was just another crazy night of her getting high. When she did drugs, it was three to four times a week," the source said.

However, sadly, Mueller's drug habits might make her lose her kids-which she knows full well, they added. "I know that she is aware that if she doesn't stop doing drugs, she is going to lose her kids [for good] ... hopefully she can stop."

Mueller's addition battle has been very public. She recently checked into rehab for the 20^th time after a relapse. In May, Mueller lost temporary custody over her 4-year-old twins, Bob and Max Sheen. The Los Angeles County Department of Children & Family Services and a judge ruled that the Mueller home was an "unsafe environment" for her boys.
