Their break-up came as a shock to Keeping Up With The Kardashians viewers, who watched their romance blossom.

On the September 21st episode of The Real, the topic of Kardashian and cheating scandals came up, since he addressed it on a recent episode of Rob & Chyna.

“Our relationship, what’s in the past is in the past. He’s moving on, he’s about to be a father, which, congratulations to him and Chyna.
"But, what I will say is, that girl was certainly not me, just saying. It definitely was not me. I absolutely never cheated on Rob.”
Knowing that everything has come full-circle, Bailon feels for her ex.
“I absolutely do relate to what he’s saying, though,” she said.
“I will say this, I think anybody who’s been in a relationship where they were cheated on or hurt, it affects you.
It affected me so much that I made it a conscious decision to not do that to the next person.”
Love jumped in to clarify that Bailon was cheated on.
Rob cheated on her!” Love to told the audience.
Bailon went on.
“He was 21 years old at the time. We were super young at the time, you guys.
