Adrienne Bailon: I never cheated on Rob Kardashian

LOS ANGELES, Sept. 21 (UPI) -- Adrienne Bailon is setting the record straight on her past relationship with Rob Kardashian.

The 32-year-old The Real host denied on Wednesday's episode that she was unfaithful to Kardashian after the reality star brought up a cheating ex-girlfriend on his E! series, Rob & Chyna.

"What I will say is: that girl was certainly not me, just sayin'. It definitely was not me. I absolutely never cheated on Rob," Bailon asserted. "I can't speak for anyone else, but I can assure you that was not me."

Kardashian had told his fiancée, Blac Chyna, on Sunday's episode of Rob & Chyna that he once dated someone who was unfaithful. Fans immediately speculated the unnamed person was either Bailon or singer Rita Ora.

"I had a really bad past relationship where the girl was cheating and having sex with so many different people," he revealed to his bride-to-be.

Bailon and Kardashian dated for two years before splitting in 2009 after the reality star cheated. Bailon addressed Kardashian's infidelity again on The Real but told her co-hosts "the past is in the past."

"I think Rob is a great guy [today]," she said. "He was twenty-one years old at the time. We were super young. This is over ten years ago, so this is such old news. With that being said, being cheated on will make you question yourself."

Bailon herself is engaged to musician Israel Houghton. Kardashian and Blac Chyna got engaged in April and announced they're expecting their first child, a daughter, the next month.
