Brooke Mueller -- No Jail in Aspen Coke Case

Brooke Mueller has just been sentenced in her Aspen cocaine case -- and as TMZ first reported, she won't spend a day behind bars.

TMZ broke the story, Brooke struck a plea deal with prosecutors back in March -- agreeing to plead guilty to one count of cocaine possession (less than 4 grams) following her Aspen drug arrest in December.

In exchange, prosecutors agreed to drop the other felony possession charge (with intent to distribute) as well as a misdemeanor assault charge.

Brooke was sentenced to one year probation and the case has been transferred to California, where Brooke lives.

But there's one big catch -- during the entire probation, Brooke is prohibited from drinking ANY alcohol whatsoever ... and must submit to random urinalysis.
