Nadya 'Octo-Mom' Suleman is in rehab for an addiction to Xanax, but sources close to her exclusively tell Breaking Celebrity News that she also struggles with alcohol, and her former hairstylist claims Nadya got so wasted while getting her hair done that she forgot whether or not she paid!

According to Stephanie O., she showed up at Nadya's home on April 17, 2012 at 6 p.m. to cut and color her hair as well as give haircuts to her two oldest children -- and not only did the children get locked away in a room, but by the time she was finished nearly five hours later, Nadya was "acting as if she was intoxicated."

"I arrived at her house at six o'clock, and as I started to cut her daughter's hair, Nadya put the eight babies in their room with a movie on," Stephanie told Breaking Celebrity News in an exclusive interview.

"Then the oldest son Elijah came and put a chair against the door, locking the babies in the room. I asked him, 'Why did you lock them in there?' His response was, 'My mom told me to do it because the babies get out if it's not locked and get into the food.'"
