So long to your teen years, Harry Styles! It appears that Kendall Jenner still lights up Harry's world like nobody else, as she has apparently been planning a huge shindig this weekend for his 20th birthday.

The One Direction hunk turns 20 on February 1, and Daily Star is reporting that Kendall, 18, has plenty of tricks up her (fashionable) sleeve to help Harry celebrate, including planning a birthday party for him in London. 

"She wanted the party to be in London so that Harry’s friends and family could all be there," reveals a source. "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 teases. We'd expect nothing less.

But that's not all Kendall is planning. She apparently is hoping that the two can enjoy a romantic getaway next week.

"Kendall’s dad [Bruce] has a beautiful cliff-top holiday home in Big Sur, California, and she has asked if she and Harry can use the mansion for a private break together," says the insider.

"She wants them to have some time alone where they can relax and enjoy each other’s company," the source adds. "Harry already has everything he wants, so she decided to organize something special they can always remember."

Sounds amazing! The two have yet to confirm that they're actually dating, but with birthday plans like these, things are definitely sounding serious.

Are you surprised that these two are getting so romantic?
