KYLIE Jenner’s 21’st birthday bash was shut down by police, according to new reports.

Page Six claim the cops were called after the party – held at Delilah - raged on past the 2am closing time.

The Keeping Up With The Kardashian’s star celebrated her big birthday with friends and family at the pink and gold themed bash.

The night started off with dinner at Craig's in West Hollywood with her closest family and friends -including Kris Jenner, Corey Gamble, Scott Disick, Malika Haaq, Khloe Kardashian and Kourtney Kardashian as well as her sister Kendall Jenner and her boyfriend Ben Simmons.

They then headed to nearby nightclub Delilah, which had a ball pit set up in the back room.

The party theme continued with the decor and there were "Kylie F***ing Jenner" lighters scattered everywhere.

Guests could choose their cup colour depending on their relationship status - red for taken, yellow for single and green for it's complicated.

A source said: "People were having fun choosing and were messing around. All of the girls were drinking together.

“Everyone was letting lose and having a great time. Even Kim was drinking and everyone was surprised.”

The police arriving wasn’t the only drama of the evening – an ambulance was also called the venue.

Parademics were seen bringing out a woman, who was lying face down on a stretcher, before loading her into an ambulance.

The identity of the woman is not yet known and it's unclear whether she was one of Kylie's party guests.

Meanwhile, Kylie’s boyfriend Travis Scott gifted her a Rolls Royce for her birthday.

Sharing a video of the big reveal on Instagram, she captioned the post: "woke up to a little fairytale ... thank you baby @travisscott (sic)"

In one of the clips, the blonde beauty steps out of her house to be greeted by hundreds of red roses, with the car parked outside the house with a red bow on.
