Kendall Jenner is still "casually dating" Ben Simmons - even though she was spotted smooching Anwar Hadid recently. 

The 'Keeping Up With the Kardashians' star set tongues wagging when she was seen locking lips with the 18-year-old model - the brother of Gigi and Bella Hadid - over the weekend, but it seems there's nothing serious going on between the pair as she's still seeing the basketball player.

A source told 'Entertainment Tonight': "Anwar and Kendall are just having fun for now. Both of them recently got out of relationships, and don't want anything too serious. 

"Kendall is best friends with Anwar's sisters, Gigi and Bella, and she respects them tremendously," the source continues. "Kendall would never want to do anything to put her relationship with Anwar's sisters in jeopardy. Kendall and Anwar have known each other for years and have always been flirtatious and this is just another sign of that. 

"The two enjoy one another's company and things could change, but for now, it's nothing serious."

Although she's seeing where it goes with Anwar, the 22-year-old model has been hanging out with Ben, 21, a lot. 

An insider told E! News: "Kendall has been out with Ben Simmons a few times and she likes him. 

"They have mutual friends and have been getting to know each other over the last few weeks. He has been spending time in L.A. with her and has been to her house. They've hung out there and have been to dinner a few times."

Kendall has had a number of high-profile relationships over the years but it seems she has a particular soft spot for NBA stars as she was previously linked to basketball players Jordan Clarkson and Blake Griffin.
