We love this cat fight!

Kylie Jenner is allegedly "furious" Kylie Minogue blocked her move to trademark the name "Kylie," and now she's out for blood! The plastic surgery princess has vowed to fight tooth and nail against the Aussie pop star.

"Kylie said that Minogue is washed up and said that she needed the rights to the name ‘Kylie’ so that she could continue to develop her brand more. She is really trying to build an empire and thinks that Minogue is the only thing standing in her way," a source dished to Radar.

We have a feeling the 19-year-old is pissed about the jab the "Can't Get You Outta My Head" songstress took at her in documents opposing the trademark application. "Ms. Jenner is a secondary reality television personality who appeared on the television series, Keeping Up With the Kardashians as a supporting character, to Ms. Jenner’s half-sisters, Kim, Khloe, and Kourtney Kardashian," the papers state.

The LipKit mogul couldn't disagree more!

"Kylie thought it was absolutely ridiculous of Minogue’s camp to refer to her as a ‘secondary reality star’ when she has 84 million more Instagram followers than Minogue. She is not going to stop fighting Minogue until she gets the exclusive rights to the name ‘Kylie.' She wants nothing more than to own Kylie.com and she intends on appealing," the source added.

This diva battle is just getting started.
