Is Rob Kardashian’s Ex Adrienne Bailon Still Missing Him? Exclusive!

Rob Kardashian has admitted it was his cheating that led to the end of his relationship with ex-girlfriend Adrienne Bailon. The couple split in 2009 after two years together — but it looks like Adrienne still isn’t finished letting Rob know what he’s missing out on.

The former Cheetah Girl rolled into the double birthday bash for basketball star Amar’e Stoudemire and rapper Fabulous on November 16 wearing a barely-there, backless dress with a plunging neckline that left little to the imagination. (We’re talking very little — she wasn’t wearing a bra under the see-through frock!) After a sit-down dinner at new NYC restaurant CATCH, the group headed upstairs to hotspot CATCH Roof for a wild Boardwalk Empire-themed soiree.

Once upstairs, “Adrienne worked the room,” a fellow partygoer tells Wetpaint Entertainment. “She held court with several different men. She didn’t leave with anyone, but she definitely got her flirt on. A bunch of different guys were trying to get her phone number.”

But, as Adrienne tweeted the next day, she may not have been vibing with all of them. “Chemistry is everything,” she tweeted. “Either you got it or…Damn…You just don’t. There’s nothing like amazing chemistry.”

We know she and Rob definitively had chemistry when they were together. The question is: Can they get it back?
