Kendall Jenner's family rented out an entire theme park for her 18th birthday party.

The 'Keeping Up with the Kardashians' star's big day isn't until Sunday (03.11.13), but she was given an early surprise when her parents Kris and Bruce Jenner and her famous siblings privately hired the Six Flags Magic Mountain park in Los Angles for her enjoyment on Tuesday (29.10.13).

Her half-sister Kim Kardashian posted a video on her Keek account, in which she is seen saying: ''We're here for Kendall's birthday party and we rented out Magic Mountain. No one else is in the entire theme park but us and the people there to greet us.

''But look, no one's even working in the concession stands. And we get to drive instead of walk. This is real lazy, but this is what Kendall wanted and it is a nice surprise for her and I'm excited for her. So happy birthday Kendall.''

Although the 17-year-old model's parents Kris and Bruce recently called time on their 22-year marriage, they were both in good spirits and got on well throughout the day -even posing for a cheery photograph with Bruce's sons Brandon and Brody.

Kris posted the snapshot onto her Instagram account, accompanied with the caption, ''Great night at Magic Mountain! @sprandoni @brodyjenner Bruce #happybirthdaykendall (sic)''
