"Real Housewives of New York" star Bethenny Frankel is slamming cast mate Ramona Singer for having "no game."

Even as she admits she can sometimes be a know-it-all, Frankel blasts Singer in a new Bravo blog post as someone who "can start something but a closer she is not."

The two reality TV stars have been feuding ever since several of the show's cast mates embarked on a recent trip to Caicos and the question of what's suitable from single women looking to date in terms of the ways they attract men became an issue.

In her post, Frankel further slammed Singer as "that girl we all knew and hated in college," taking great exception with the way she perceived Singer to have behaved in trying to gain the attention of one man in particular during their trip.

"This is the new and improved selfish, single Ramona," she wrote. "Oh joy. She heard that guy was rich and single, and like a desperate barracunda, she went in for the kill."

The 43-year-old has seemingly been taking everyone to task in recent days. Earlier this week she appealed a Manhattan Court judge's decision ordering her to pay spousal to ex-husband Jason Hoppy and allowing him to continue living in the Tribeca apartment they once shared.

RadarOnline reports the two purchased the property through a trust, but in her filing Frankel insists she put up all the money. Lawyers for Frankel also contend the two parties had a binding, prenuptial agreement entered into in 2010 stipulating that neither would seek spousal support from the other should their union dissolve.

In the end, Frankel charges that since the money used to purchase the property solely came from her, Hoppy should not be awarded the property as a matter of New York City law finding that once a trust has been invalidated the person supplying the money is awarded the property.
