Looks like Kylie Jenner has made an enemy of Kylie Minogue.

The 47-year-old singer is trying to legally stop the 18-year-old "Keeping Up With the Kardashians" star from trademarking her first name, according to the World Intellectual Property Review.

Citing the potential for brand "dilution" and consumer confusion, Minogue, who owns trademarks on "Kylie Minogue darling," "Lucky - the Kylie Minogue musical" and "Kylie Minogue," filed two oppositions this month to Jenner's 2015 trademark request.

In the legal documents, KDB, a company that represents the singer's business pursuits, called Jenner "a secondary reality television personality who appeared on the television series Keeping Up With the Kardashians as a supporting character."

The complaints go on to reference public controversies that have gotten Jenner in hot water with various groups.

"Ms. Jenner is active on social media where her photographic exhibitionism and controversial posts have drawn criticism from, e.g., the Disability Rights and African-American communities," Minogue's rep says in the docs.

According to E! News, Jenner's application requests the right to trademark "Kylie" for use in "entertainment in the nature of providing information by means of a global computer network in the fields of entertainment, fashion and pop culture."

Kylie's sister, Kendall, meanwhile, has applied to trademark her name in the contexts of hair accessories, clothing, beauty products and other services.
