KYLIE Jenner should be so lucky.

The teen reality star and model wants to trademark her first name, but there’s just one problem: Our Kylie put the moniker in lights before Jenner was even born.

Six months after the trademark application was advertised, Kylie Minogue has come out guns blazing.

Minogue’s representatives last week filed a notice of opposition with the US Patent and Trademark Office, arguing if it approved Jenner’s application, it would cause confusion and dilute her brand, World Intellectual Property Review reports.

KDB, a Melbourne company representing Minogue, 47, filed a notice of opposition to the application last Monday, citing existing trademark registrations for the term ‘Kylie’ that cover entertainment services and music recordings.

The documents reportedly describe Jenner as a “secondary reality television personality who appeared on the television series Keeping Up With the Kardashians as a supporting character”, who has been criticised by African American communities and disability rights groups.

The 18-year-old daughter of Caitlyn and Kris Jenner has been involved in a number of public gaffes in the past year, including posing in a wheelchair in a fashion shoot for Interview magazine, and reportedly buying her mixed race friend a birthday cake with the message “happy birthday N****” scrawled in icing.

Jenner’s trademark application sought protection for the term ‘Kylie’ in connection with advertising services.

Minogue also owns trademarks for the terms ‘Kylie Minogue darling’, ‘Lucky — the Kylie Minogue musical’ and ‘Kylie Minogue’.

Her debut album, which sold more than 500,000 copies in the United States, was called ‘Kylie’.

She has owned the domain name kylie.com since August 21, 1996, a year before Jenner was born, The Mirror reports.

Minogue has reportedly hired lawyer Rebeccah Gan, of Washington DC firm Wenderoth LLP, which advertises itself as “an Intellectual Property firm with one primary focus — prosecution”.

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

Minogue has tweeted in reference to the dispute, writing: “Hello... My name is KYLIE #lightyears”, a lyric from her 2000 song Light Years.

Supporters responded by tweeting: “The one and only.”

We hope the stoush is resolved in our Kylie’s favour; after all, it’s better the devil you know.
