Kendall Jenner apparently wants some "time alone" with Harry Styles.

The One Direction heartthrob will be turning 20 on Saturday, and Kendall is hoping to enjoy the day with him.

The pair share a close friendship, and have been linked romantically after being spotted out together on numerous occasions.

Sources say 18-year-old Kendall is keen to whisk Harry away to a cliff-top holiday home owned by her family in California.

"[Kendall] has asked if she and Harry can use the mansion for a private break together. She wants them to have some time alone where they can relax and enjoy each other's company.

"Harry already has everything he wants, so she decided to organise something special they can always remember," a source revealed to British newspaper Daily Star.

As well as the getaway, Kendall is thought to be helping with the arrangements for Harry's celebrations in the UK.

The popstar will be treated to a London bash with all of his friends, family and work colleagues.

"Kendall is in charge of organising the party, alongside Radio 1 DJ Nick Grimshaw. She wanted the party to be in London so that Harry's friends and family could all be there.

"The rest of One Direction and a whole host of other celebs will be on the guest list. It won't be a tame affair, and Kendall will pull out all the stops to make sure it's a night to remember," the source continued.

Harry and Kendall already holidayed together this year when they managed to squeeze in a New Year break at the Mammoth Mountain ski resort in California.

"At first, Kendall and Harry were shy around each other, but they held hands after skiing and later in the hot tub he was rubbing her back and neck," an insider previously told British magazine Heat.
