It was the celebrity relationship teenage dreams are made of - One Direction heartthrob dating model Kardashian Kendall Jenner.
But all good things must come to an end.
It's reported that Jenner and Styles have split after three months together due to work commitments.
"Kendall has been focusing on her modelling and Harry is preparing for work on the band's fourth album, as well as their stadium tour," a source told The Sun.
"The reality is that with everything they both have going on, it's impossible to sustain anything serious."
Kendall's modelling career is going from strength to strength as she made her New York Fashion Week debut walking for Marc by Marc Jacobs and also hitting the catwalk at London Fashion Week.
Speaking to Into The Gloss before her debut, she said: "The New York fashion scene is crazy, madness, but I love the energy. I love everything about it—like the hair and makeup today, it’s incredible. I’ve never had my eyebrows bleached; I don’t even look like myself!
"I’m a little nervous for the show, but I’m really excited. It’s my first runway show, so I’ve been practicing. I feel like everybody has their own individual walk, and that’s what makes someone so special. Maybe I’ll run down the runway!"
