Rob Kardashian’s bliss from his engagement to girlfriend Blac Chyna might be short-lived. If it’s true the Kardashian sisters are not happy about the proposal, they’re not the only ones. “Love & Hip Hop: Atlanta” cast member Amber Priddy dropped a bombshell Tuesday, the same day of the engagement, when she claimed Kardashian cheated on Blac Chyna -- with her.

Even though she made her Instagram account private, blogs like The Shade Room and Media Take Out preserved the images through screen shots. Kardashian’s name had a blue heart next to it.

In March he reportedly said: “I’m in Atlanta.” To which Priddy responded, “I see. Didn’t want to get u in trouble lol.” He wrote back, “Lol. Where r u?” When she said she was working at the strip club, “Goldrush,” he said he would go see her.

 

YES !...!...!

If the messages posted to Instagram are authentic, Kardashian, 29, was not happy about her posting the texts. “Why would u post our texts like that?” he supposedly wrote. “U must be on some crazy s--- to be doing that to someone on the day of their engagement.” Even though the texts don’t incriminate Kardashian, they do look suspicious. It doesn’t help that he has a bad reputation, either. He famously cheated on ex-girlfriend Adrienne Bailon.

Neither Blac Chyna nor Kardashian have responded to the cheating rumors. A day earlier, the model confirmed she was engaged to the failed sock designer. “I'm so blessed and honored to have good man in my life, I love you @robkardashian!” she wrote.

Ben Baller, the jeweler who helped the former reality star design the 7-carat ring, wished his friend well. "Rob, I have never seen you this happy before and I've known you since you were a teenager," Baller wrote. "I'm glad you came to your day one homie to get this massive [ring] for your lady. You know I don't play when it comes to diamonds. God bless."

It’s more than anyone from the Kardashian-Jenner camp have said. None of the ladies have issued a statement since their brother got down on one knee.
