Harry Styles and Kendall Jenner dating rumors are heating up, following Kendall Jenner's recent Instagram photos of her in London. Did she meet up with Harry Styles across the pond?

According to MTV UK, Kendall Jenner, 18, made a quick visit to London this weekend, judging by her Instagram photos. She posted a few pics of herself looking at the London skyline, including the Houses of Parliament on Saturday.

She captioned the photo: "hey Ben!", referring to Big Ben, and "good morning London."

Though Harry Styles was still in Cannes for the NRJ Music Awards with One Direction at the time, Hollywood Life reports that rumors are saying Harry flew back to London to reunite with Kendall over the weekend.

Upon returning home to Los Angeles on Sunday evening, Kendall posted a photo from back home in Calabasas on Monday. She showed off her huge family Christmas tree, with the caption: "coming home to this... not too shabby."

Meanwhile, Harry was back with One Direction at Wembley with a live performance on the "X Factor," Daily Mail reports.

But when E! News talked to Kendall earlier about her relationship with Harry, she said cryptically: "Nothing to say... No deets."

The model and half-sister of Kim Kardashian told E! News at the AMAs that she and Styles are "friends," adding "he's cool."

According to the website, Harry Styles and Kendall Jenner dating rumors first began around November 20, when they were spotted leaving a late dinner date at Craig's in West Hollywood. On November 25, Harry reportedly took Kendall out for another meal, according to Us Weekly.

The couple were also spotted emerging from the Gansevoort Hotel in New York on December 7.
