Kim Richards made it a whole month in rehab, but she bailed over the weekend, fleeing under cover of darkness in the middle of the night.
The reasons why, and her current whereabouts, are not known.
According to previous reports, Kim committed to a 90-day stay at the Malibu facility where she was receiving treatment ... a month ago.
In other words, it's safe to assume she did not complete the program she was taking part in, and just took off for undisclosed reasons.
TMZ reports that Kim simply had enough, and wasn't getting along with the staff, including the doctors who had been treating her.
The timing is pretty curious, though, since the rest of her famous family was across the pond for Nicky Hilton's wedding in London.
Her sister, fellow Real Housewives of Beverly Hills star Kyle Richards, has been taking a tough love approach to Kim for months.
Things had been going well for Kim in treatment, in fairness.
She was all smiles July 4 when family visited, and we heard she was getting back with her ex Monty Brinson, and back into acting.
