Kendall Jenner ''seems a bit more serious'' with Ben Simmons.

The 'Keeping Up With The Kardashians' star has been romantically linked with the NBA player for a while now and things are said to be heating up between the pair.

One source shared: ''Kendall and Ben have spent the past few days together in Los Angeles. They do seem a bit more serious.''

Whilst another insider added to People magazine: ''They seem to have a great time together. Kendall looks happy with Ben. You can tell she is enjoying her summer.''

Kendall is reportedly living with her boyfriend Ben at a mansion in Los Angeles, California.

A source said at the time: ''Ben is renting the house. Kendall is not on the lease. It's a gorgeous house, so it makes sense that she wants to stay over as much as possible. Kendall and Ben have spent the past few days together in Los Angeles. They do seem a bit more serious.''

The brunette beauty had previously been romantically linked to Ben, 21, earlier this year after they were spotted on a string of dates in LA, but she threw a spanner in the works earlier this month when she was spotted smooching Anwar Hadid - the brother of Gigi and Bella Hadid - but they've played it down by claiming they were ''best friends''.

A source said at the time: ''Kendall is best friends with Anwar's sisters, Gigi and Bella, and she respects them tremendously. 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.''
