Harry Styles back with Kendall Jenner?

Harry Styles has fueled speculation he is dating Kendall Jenner again.

The One Direction hunk – who was first romantically linked to the brunette beauty in 2013 – reportedly sneaked into the ‘Keeping up With the Kardashians’ star’s 21st birthday party at Catch in Los Angeles, arriving at the venue through a back door shortly after watching her brother-in-law Kanye West’s performance in the city.

And Harry, 22, is said to have also made a visit to Kendall’s house on the morning of her birthday.

A source told HollywoodLife.com: "Harry wanted to be one of the first people Kendall saw on her actual birthday, and so he came by to personally deliver his birthday gift to the supermodel."

Harry and Kendall have dated numerous times in the past, most recently in September but it was claimed they had gone their separate ways just a few weeks later because the reality star didn’t want to get "caught up" in the ‘Dunkirk’ actor’s "drama".

And it was also claimed the ‘Little Things’ singer is reluctant to settle down.

An insider explained: "Harry has always been ‘that guy’ for Kendall. She would love to be in a real relationship with him, but he’s always had issues settling down in the past with her because he has that rock star mentality."

Meanwhile, Kendall’s sister, Khloe Kardashian, recently revealed her younger sibling got so drunk at her birthday bash, she forgot she had been gifted a Rolls Royce.

Khloe said: "We go outside and there’s a guy with a Rolls Royce, we’re like ‘What’s the gift, the guy or the Rolls?’

"And then the guy just hands her the keys to this car. We don’t know who this guy is, he’s some prince.

"I was like ‘Is this a joke?’ I think on my 21st birthday I got like a dinner and a purse or something.

"The next morning I asked her about it and she said, ‘Oh my God I forgot I got a car!’ That’s how drunk she was."
