Burn! Three years after splitting with Rob Kardashian, "The Real" co-host Adrienne Bailon has revealed what really went down when the reality star received a letter from her supposed "new boyfriend," post-breakup in 2010.

During a previously aired episode of "Keeping Up With the Kardashians," fans saw a disheveled Kardashian reading aloud a letter he believed was from Bailon's new man -- in which he implored Kardashian to stop calling Bailon. But what Kardashian, 26, didn't know at the time was that the infamous letter was actually written by the former "Cheetah Girl" herself!

"I was my own fake boyfriend," she admitted. "What all ya'll thought was that it was written by my boyfriend. It was not written by a boyfriend," she exclaimed to her cast members. "That was written by me and my girl sitting on the sofa one day deciding to ourselves, 'Well, how can we make him stop calling me?'"

Adding gleefully, "I got left alone. I think it worked!"

Bailon, 29, and Kardashian dated for two years until the "Kourtney & Kim Take Miami" star admitted to cheating in 2010. "I was embarrassed and basically said, 'I want nothing to do with you,'" Bailon recalled.

Though the pair initially decided to never go public with the details, Bailon did show some regret looking back on the whole ordeal. "I felt so bad because at the time there was so many rumors that I was dating [rapper] Fabolous. They actually pinned it on him."
