Ramona Singer star of the The Real Housewives of New York has been labeled as a "total b*tch" after she reportedly ran into her old friend, Jill Zarin, at a private club in London.

"Jill ran into Ramona and Ramona was a total b*tch to her," a source snitched told Radar Online. "Jill was with Juliet [Angus] from Ladies of London holding court at a prime table," the source said. "Ramona walked in, and Jill was excited to see her."

The bad blood between them was apparently news to Jill, who was happy to see Ramona.

"Jill walked over to Ramona to say hello and wanted to invite Ramona to sit at her table. They made eye contact, and Ramona turned her back and started walking the other way," the source told Radar.

"When Jill caught up with Ramona, Ramona completely ignored her and acted like she didn't know her. Jill was visibly upset and was tearing up as she turned around and walked back to her table."

Jill was reportedly sad about it, but not for long. Fans of the show will not be surprised by Ramona's cold actions. She is frequently accused of snubbing her friends while in the company of others.
