Adrienne Bailon's feud with the Kardashians is just heating up.

Bailon, who rose to fame with "The Cheetah Girls" and now co-hosts the talk-variety show "The Real", took to Instagram to defend herself after her ex-beau Robert Kardashian and his sisters, Kim and Khloe, called her out on Twitter for making "offensive" comments about their relationship.

On Thursday, the 30-year-old celeb shared a personal post, saying: "Fame and career are two different things. I've always had a career. I have been working hard since I was 15 years old. Being someone's 'girlfriend' was never what I wanted to be famous for."

Bailon further wrote: "What makes you 'famous' isn't always what you want to be 'labeled' as, or known for. If anyone should understand that...It should be you."

The actress has 1.25 million followers on Instagram and the post received more than 26,000 likes. Hundreds of her followers also left encouraging comments on her post and sent their support.

The misunderstanding between Bailon and the Kardashians started when the former Cheetah Girl opened up about her past relationship with Robert Kardashian.

The pair began dating in 2007, getting tattoos of each other's names on their bodies. They called it quits in 2009 when Rob reportedly cheated on the actress.

In her interview with Latina magazine, Bailon said that Rob "was so disloyal" and, eventually, "he messed up".

She also told the magazine, "To be stuck with that Kardashian label, that was so hurtful to me and to my career".

Bailon admitted that the she felt "bothered" when others would wonder why she would not give Rob another chance and forgive him for cheating.

To the defense of a Kardashian member, Kim and Khloe were not impressed when Bailon made light of the Kardashian name, their personal label that has enabled the family to make millions.

The two sisters took to Twitter and wrote their own comments that sparked up the feud. While Khloe thought that she and Bailon "were cool" back in the day, Kim thought it was "funny" for Bailon to say that Rob had damaged her career.

Kim wrote, "The only reason she has this article is bc she is talking about a Kardashian".
