Harry Styles was reportedly spotted outside Kendall Jenner's hotel in the early hours of Sunday morning.
The One Direction star and the half-sister of Kim, Khloé and Kourtney Kardashian have been rumoured to be dating for some time.
Harry, Niall Horan, Zayn Malik, Louis Tomlinson and Liam Payne had been attending the NRJ Music Awards at the Cannes Festival Palace in France over the weekend.
However, rather than celebrating the band's wins in the International Duo/Group of the Year and Video of the Year categories the 19-year-old jetted back to the UK alone.
According to the MailOnline, the curly-haired heartthrob was spotted outside the 18-year-old's London hotel at 2.20am on Sunday.
Despite both having busy schedules, Harry and Kendall also squeezed in a rendezvous in America earlier this month.
"Harry and Kendall have been texting each other constantly since they went out in New York last week," a source told British newspaper The Daily Mirror.
"They're both really into each other and although they're playing it down to their friends, they're both excited about the relationship."
An insider also told HollywoodLife: "They could definitely be considered girlfriend-boyfriend bound... Harry likes [Kendall]. He's having lots of fun with her, and thinks she's cool and hot. And he likes that Kendall is trying really hard to get him for her own exclusive relationship."
It's unsure whether model Kendall is in the UK for work or to see the British popstar.
So far Harry has remained coy about their friendship, insisting he "doesn't know" if they are romantically involved.
