Kendall Jenner is reportedly "calling the shots" with Harry Styles.

The 18-year-old reality star and One Direction hunk have been linked since last November after being spotted out several times. They even went on a skiing holiday together in January.

While there have been rumours the pair have called their romance off, insiders insist they are still seeing each other. However, Kendall is reportedly keen to take the reins with the 20-year-old lothario.

"It's like turning 18 changed something in her and she's told Harry she wants to slow the pace of their romance. She's said if he's serious about her, she'll be the one calling the shots and there's no way she's going to let him break her heart," a pal told British magazine Look.

"They're still on, just slowing it down. Kendall couldn't believe the amount of attention she suddenly found herself getting, and the sheer pressure of dating someone with such a huge fan base. She may be younger than Harry, and she's not a popstar, but she is the boss!"

Harry previously dated singer Taylor Swift and was also romantically linked to model Cara Delevingne. It is thought his eventful love life has made Kendall more held back.

"She suggested they cool things down and see how they go, as they're both busy with work. Harry was very surprised at how cool she was in comparison to his exes. So now he's more attracted to her than ever," a source added.

"Like the world, she saw how heartbroken he left Taylor Swift. She also feels a bit weird about the fact he and Cara Delevingne had a thing - especially now they're such good friends after meeting at London Fashion Week. But she's a very confident young woman, and now Harry's eating out of the palm of her hand. When he calls or texts, she often doesn't reply. He finds this astonishing - and alluring."

However, further reports suggest Harry is already moving on from Kendall. It's been claimed he enjoyed a flirtation with 35-year-old The Kills star Alison Mosshart after they met at London Fashion Week.
