Bailon made the announcement Wednesday on "The Real," her new daytime talk show, US magazine reported. She told the other hosts -- Tamar Braxton, Tamera Mowry-Housley, Loni Love and Jeannie Mai -- a bad decision was made worse by the length of Kardashian's name.
"It does not feel good. You could smell your flesh burning," she said, describing the process of laser removal.
Kardashian, 26, who starred with the rest of his family on "Keeping Up with the Kardashians," and Bailon kept company between 2007 and 2009. During that time, she got "Robert A. Kardashian" on her fanny, while he had "Adrienne E. Bailon" on his ribcage.
"It's awful. Ten-letter last name, Kardashian. It's pretty bad, yeah," Bailon said. "Now that is a ratchet tattoo. I made a very bad decision. Don't follow my example."
