Khloe Kardashian jets off on holiday with basketball star Tristan Thompson

Khloe Kardashian has jetted off on holiday with basketball star Tristan Thompson.

The 32-year-old reality TV star is spending the weekend in Cabo San Lucas, Mexico with the 25-year-old Cleveland Cavaliers player, leading to speculation that they have started dating.

A source told E! News that the pair are "just friends" and revealed they went clubbing together last week where "they were laughing a lot of the time but no kissing or holding hands".

However, the pair have been spending time together over the past few weeks.

TMZ reports they spent the day together at a Beverly Hills mansion last week, while they also recently partied together at Bootsy Bellows nightclub in West Hollywood.

Khloe was linked to New York Giants football player Odell Beckham Jr in May, when the pair were pictured flirting at a party at Drake’s house, but the 23-year-old star revealed he had actually been interested in someone else at the time and the photos ruined it.

He explained: "Whoever was there taking the pictures inside of a private party, inside of a private area of the house – we were in the kitchen of the house, where there was only like 15 people.

"It’s just kind of like…”dating?’ I just met this person. This is maybe the second conversation we’ve had."

"Things go like that and then some other girl that I may have been talking to hear about it, and now it’s more drama, more commotion in my life.

"And I’m sitting here trying to explain my situation to somebody, and it’s really not even a situation."

While Khloe appeared to admit they were flirting, she also shot down reports of a romance.

She tweeted: "Sorry to burst your bubble. When a couple drinks, a little flirting and an invasion of privacy collide things may look crazy… However…this ain’t that and that ain’t this (sic)."
