Kendall Jenner celebrated her 21st birthday on Wednesday evening.

And the Keeping Up With The Kardashians star appeared to be enjoying her first cocktail as well during her after party at Delilah in West Hollywood (her first party was at Catch).

Her younger sister Kylie shared a Snapchat video from inside the bash. The Vogue model was holding what appeared to be a vodka tonic with a lime in her hand.

People also reported that Kendall had plenty of men around, including Harry Styles, Jordan Clarkson and Travis Scott.

Kim Kardashian and Kanye West also made a 'low key' appearance, according to the site. The 36-year-old has been out in public few times since her October 3 robbery in Paris. 'They were chill all night,' said a source that noted the couple arrive just before midnight.

'Kim got on the mic at one point and said something funny and that was about it. She seemed pretty upbeat,' added the source.

In the state of California the legal drinking age is 21.

A source told DailyMail.com that there were 21 bottles of Perrier-Jouët Belle Epoque Champagne (which sell for $500 a bottle) at the event.

The star was also presented with a cake 'featuring a throwback photo of her in a purple tutu and a massive jewel-studded Perrier-Jouët Belle Epoque Methusaleh with her name on it.'

It was added: 'Kim and Kris sang Happy Birthday to Kendall at midnight.'

Drinking is new for Kendall, it appears. In July her sister Khloe told Elle.com that the Calvin Klein spokesperson will not hit the bar.

'Kendall isn't into it,' Khloe, 32, said.

Clear liquid: The E! star was also seen putting the glass down on the table then picking it up again. It could have also just been a glass of water

New thing? Drinking is new for Kendall, it appears. In July her sister Khloe told Elle.com 'Kendall isn't into it, even when Kendall goes to Europe where the drinking age is 18, she's never — Kendall's really focused and determined'

'Even when Kendall goes to Europe where the drinking age is 18, she's never — Kendall's really focused and determined.'

But on Thursday, Kendall wrote on her website kendallj.com that she had a signature cocktail already,

'I'm not really a person "who hits the club" regularly and I don't see that changing now that I'm 21,' she wrote.

'I'm looking forward to ordering drinks at dinner, though, and 1942 on the rocks with a slice of orange is what I'll be sipping! Tequila is surprisingly easy to drink throughout the night (as long as you don't overdo it)!'

It was Kendall Jenner's birthday party last night and if she wanted to wear two outfits then that's exactly what she was going to do.

And while they were different they were equally sexy. First there was the sheer embellished catsuit by Julien Macdonald which was followed by this super slinky slip dress by LaBourjoisie.

Custom made by the Kuwaiti fashion house it's a very revealing mini with a low back, side splits and a draped plunging neckline. And let's not forget all those glittering Swarovski crystals. She looks like a very chic disco ball.

As it was made just for Ms Jenner it's not available to buy but you can click (right) to take a closer look at the label and its most recent collections. Or why not recreate Kendall's look in time for party season?

We've found some sparkly slips that won't break the bank below.

Khloe then added on her site khloewithak: 'My little Kendall is all grown up! I could not be more proud of the amazing (not to mention fierce AF!!!!) young woman that you have become. Your first legal drink is on me, boo! Happy birthday!'

Kylie wrote on kyliejenner.com: 'Happy 21st birthday to my partner in crime since Day 1—literally! You've always been by my side and I'm glad we are still so close today. I hope you have the best birthday ever, Kendall!!! ❤'

In the past, Kendall has said she stays away from most vices overall. She wrote on her website kendallj.com that she doesn't like coffee and has never smoked.

The star has also complained that she suffers from sleep issues which would suggest she is careful with her health.

In a clip from an upcoming episode of Keeping Up With The Kardashian she tells her mother Kris she can't move when she wakes up in the middle of the night.

The leggy wonder looked as healthy as can be as she sipped out of the small tumbler glass while mingling with pals at Delilah.

She was also seen putting the glass down on the table then picking it up again.

People reported that Styles, Clarkson and Scott all flocked around Kendall at her after party.
