It’s a special artist who becomes a global household name without the need to tack on a surname. Think Madonna, Beyoncé and Adele. The late rockers Elvis and Lemmy didn’t need to announce their family names. Think Usher and Prince, Sia and Kylie. Turns out another Kylie wants the name all to herself.

Kylie Jenner, the teenage model and star of reality series Keeping Up With the Kardashians, has applied to trademark her first name in the U.S. Problem is Kylie Minogue has been performing as “Kylie” since before Jenner was born.

Jenner is seeking protection for the name “Kylie” in connection with advertising services, according to World Intellectual Property Review, though Minogue’s reps last week filed a notice of opposition to the application.

KDB, an Australian-based business representing Minogue, argues that if the U.S. Patent and Trademark Office approved Jenner’s application then it would cause confusion among consumers and dilute the pop singer’s brand.

In its opposition, KDB said Jenner was a ““secondary reality television personality” who appeared as “a supporting character” on Keeping Up With the Kardashians, and who has been criticized by disability rights groups and African American communities.

Minogue has addressed the dispute in a message to her 2.3 million Twitter followers.

Minogue has sold more than 65 million albums over her career. Her trophy room includes Brit Awards, Grammys and in 2007 she became the first-ever woman (and first foreigner) to receive Britain’s prestigious Music Industry Trusts’ Award. In 2011, she was inducted into the ARIA Hall of Fame. She has owned the domain name kylie.com since Aug. 21, 1996, a year before Jenner was born, The Mirror reports.

Jenner has also filed a trademark application for the name "Kylie" in connection with entertainment services, published for opposition last Tuesday.
