It's Kylie vs. Kylie.
Reality star Kylie Jenner and Australian singer Kylie Minogue are currently engaged in some legal drama, after 18-year-old Jenner applied to trademark her first name in the United States. Jenner is seeking protection for the name "Kylie" in connection with advertising services, according to World Intellectual Property Review, though obviously, that doesn't sit well with 47-year-old Minogue.
Minogue's reps filed a notice of opposition on Feb. 22 to Jenner's application, claiming it would cause confusion among consumers and dilute the "Can't Get You Out of My Head" singer's brand. The documents call Jenner "a secondary television personality," and alludes to a few controversies she's been embroiled in over the years.

"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 (i.e., the Kardashians)," the filing notes. "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."
The documents seem to be making reference to the Interview magazine photoshoot of Jenner in a wheelchair that some felt was insensitive.
Minogue's legal filing also points out that the singer has been famous longer than Kylie, and has owned the domain name www.kylie.com since 1996 -- a year before Jenner was born.
"Kylie has been in the entertainment industry since 1979, and launched her first album titled 'KYLIE' in 1988," the documents state. "To date, Kylie has worldwide record sales of over 80 million records and tours regularly around the globe, including in the United States."
Minogue seemed to address the legal issue with a cryptic post on Twitter. "Hello..... My name is KYLIE #lightyears," she wrote.
"My name is Kylie" is a lyric from her song "Light Years," off her 2000 album of the same title.

For her part, Jenner has had a few undeniably successful business ventures. Last December, her lip kit sold out in seconds, and she and her 20-year-old sister, Kendall Jenner, debuted a new fashion line in January. The sisters' latest venture is a new gaming app, "Kendall & Kylie," which takes fans on adventures through Hollywood. She currently has 53 million followers on Instagram.
ET has reached out to both camps for comment.
Jenner recently opened up about her much talked-about social media presence, which she dubbed her "alter-ego."
"It's not that I don't want to do it ... Yeah, actually I kind of just don't want to do it any more," she surprisingly confessed to Wonderland magazine. "Honestly. But I've always been like that. I want to be a businesswoman and be behind-the-scenes. Kylie Jenner needs to retire."
