Ramona Singer has accused Sonja Morgan of having a substance abuse issue for years, but is she the one who is really suffering from an addiction?
On an episode of Watch What Happens Live, Singer revealed her Real Housewives of New York co-star mixes alcohol and pills. But Morgan, 52, shot back by admitting her friend is the one who is "on pills!"
"Ramona's diet pill problem has been an ongoing battle the past few years," a source told In Touch. "It began when she went to see a doctor to lose some weight."
The weight-loss pills reportedly helped Singer slim down and give her an energy boost.
"Ramona needs to stop acting like everything is perfect," the insider continued.
But Singer denied the claims made by her best friend.
"I don't use diet pills and never have," she told the magazine. "Perhaps if I did, I would not be 5 pounds over my normal weight!"
On a recent episode, Singer told Morgan she wasn't invited to a party thrown by Bethenny Frankel because of her "embarrassingly drunk" behavior.
"You've gotten worse than ever," Singer told her. "I need to tell you this."
