The 21-year-old model and reality star has reportedly struck up a relationship with the Los Angeles Clippers player, and although sources say they are definitely seeing one another "romantically", they insist the coupling is "nothing serious".

An insider told People magazine: "She's seeing Blake romantically. It's nothing serious. She has been in LA a lot lately, and is having fun.

"Work will soon take over her life again, so who knows what will happen will Blake then. She is having fun right now and that's all that matters to her. She takes her career very seriously and that's her number one priority right now."

The 'Keeping Up with the Kardashians' star fuelled romance rumours with Blake earlier this week after the pair were spotted enjoying a string of "cozy" dates together.

One onlooker said recently: "They sat next to each other and looked cozy. They weren't kissing, but definitely acted like they're seeing each other. They flirted and seemed happy together."

For the past year, Kendall has been romantically linked to rapper A$AP Rocky, but sources say the brunette beauty isn't in a position to settle down and is enjoying "keeping her options open".

A source said: "Kendall is keeping her options open. She's still dating A$AP Rocky as well, but she and Blake are hanging out, and there's potential there."

However, despite claims she isn't ready to settle down, a source insisted back in June that her relationship with the 28-year-old 'L$D' rapper was getting "serious".

They said: "They're definitely still hanging out and are progressively getting more serious."

It has been reported the raven-haired beauty and A$AP Rocky have been friends with one another for a long time, but their friendship progressed in 2016 when they were spotted in Paris, France, together.
