It looks like there is another Real Housewives of New York feud heating up as LuAnn De Lesseps is slamming her co-star Sonja Morgan for not supporting her recent clothing launch. The leggy New York socialite is adding fuel to the fire by saying that her friendship with Sonja feels like a "façade" for the television cameras.

"I was hurt that Sonja not only did not do anything for me, she put something out on her own style and fashion," LuAnn told Radar Online in an interview, "I felt bad. I felt like this isn't the friend that I know."

While other Real Housewives of New York stars such as Jill Zarin and Kelly Bensimon were on hand for LuAnn's ShopHQ clothing launch in May, she says she was very surprised that Sonja was the only person who was a no-show at the event.

"Sonja and I have always been really close and I have always been there for her," she adds. "So I was just surprised that she was not supportive of this big day for me."

The reality television star also says that their friendship took a turn for the worst when Sonja posted a message on her Instagram account about her own personal style and expertise on the same day as LuAnn's launch.

"We've been friends for a long time, and have always been close, but it has been strained recently," LuAnn adds. "I know she's had a lot of problems and a lot of issues going on, but I've always been there for her. I was surprised when she wasn't there for me."
