'RHONY' Kelly Bensimon vs. Bethenny Frankel [VIDEO]: Former Star Rejoins Bravo Series

Bethenny Frankel might have just reclaimed her spot on the Real Housewives of New York City, but it seems like she is already dealing with her fair share of drama. During season seven, she has already had to go up against fellow veteran, Ramona Singer, but it looks like another blast from the past is about to ruffle Frankel's feathers. When you think of the most intense RHONY fight, we are sure that Bethenny and Kelly Bensimon's scary island blowout comes to mind. The two girls are about to reunite with each other at Luann De Lesseps' girl's night out on tonight's all-new episode.

In a clip that as posted to Bravo TV, the gals all meet for a little night out on the town and Luann tells the camera that she has decided to invite all her single friends for the G.N.O (girls night out). While we are sure that Bethenny was a little apprehensive to see Ramona at the festivities after their blowout during last week's episode, it might be her run in with Bensimon that could be even more awkward for the RHONY star.

According to E! News, Luann says she ran into Kelly and decided to invite her to the get-together at the last minute.

"It's girls night, so I invited my single friends," the Countess explained. "And Kelly, I happened to run into. She's a sweetheart. She's just really cool."

From the preview, fans only get to see a little bit of Frankel's reaction, as she seems more than shocked to see Kelly when she walks into the bar.

"Really? Kelly Bensimon? That is so 2000 and who cares," Bethenny says.

The all-new episode airs at 9 p.m. on Bravo.
