Kendall Jenner and her new beau Ben Simmons enjoyed a hot tub date at the Waldorf Astoria in Beverly Hills on Tuesday.

The 'Keeping Up with the Kardashians' star and the 21-year-old athlete drank margaritas and looked super cosy as they had their private area to use the rooftop facilities at the luxury hotel.

The 22-year-old model was wearing a slinky blue swimsuit, whilst the hunky sportsman rocked a casual 'Sister Act 2' tee and bright orange Givenchy swimming shorts.

An onlooker told 'Entertainment Tonight': "Kendall and Ben were getting cosy in the hot tub.

"They snuggled up and looked happy together!"

It seems things are hotting for the couple, as Kendall is reportedly living with Ben now at a mansion in Los Angeles.

A source said recently: "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 reality star had previously been romantically linked to Ben earlier this year after they were spotted on a string of dates in La La Land, but she threw a spanner in the works last month when she was spotted smooching Anwar Hadid - the brother of Gigi and Bella Hadid - but they 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."
