It's Kylie Minogue versus Kylie Jenner in a battle for who owns their name

Kylie Minogue is trying to stop Kylie Jenner from using "Kylie" as a trademark in America.

And the singer's lawyers aren't pulling any punches.

They've filed documents describing the Keeping up with the Kardashians star as a "secondary reality television personality" who participates in "photo exhibitionism".

They also say giving Kylie J the trademark could damage Kylie M and her other trademarks.

The legal papers from KDB refer to her as a "home-schooled graduate," saying her "photographic exhibitionism and controversial posts have drawn criticism from, for example, the disability rights and African-American communities".

That could be referring to when Kylie J posed in a wheelchair for Interview magazine - or the criticism she got last year after posting Instagram snaps of her cornrow hairstyle.

KDB uses very different words to describe the singer though - calling her an "internationally renowned performing artist, humanitarian, and breast cancer activist".

The document also lists a number of US trademarks the Aussie already has for variations of her name - which cover clothing, entertainment, music, cosmetics and more.

Apparently, Kylie M also registered her website address, kylie.com, in 1996 - before Kylie Jenner was even born.

It's going to be an interesting fight. Because while Kylie M is still a star in the UK, she's never been that big in the States - and Kylie J is by far the more famous over there.

Although Kylie J doesn't have her "Kylie" trademark yet, it looks like she's has been using the name for her own beauty products.

Kylie Jenner lip gloss.

The singer's fans are backing Kylie M's claim, tweeting #TheresOnlyOneKylie.

"Take a seat. Open your ears. Learn."

"She's #TooMinogueForJenner".

Others claim there can only be one Kylie - Kylie M - because they don't even known who Jenner is.

"What is a Kardashian? Or a Jenner?"

There's no word yet on what Kylie J - or indeed her lawyers - think about all this.
