The besties partied into the wee hours at the Nice Guy in West Hollywood, so were obviously needing a pick-me-up.

The birthday girl and her 20-year-old model pal stopped by celeb-loved healthy restaurant Kreation.

Perhaps feeling low on energy, Kendall - who was driving - stayed in the car as Hailey dashed in to grab some reviving treats.

Luxe up your look in a lace playsuit by Alexis

Hailey Baldwin didn't attend the American Music Awards last night but she did join her friends at Justin Bieber's after party.

And while Gigi Hadid and Kylie Jenner both wore pieces by British label House of CB, Hailey showed off her impressive stems in a cute playsuit by Alexis. We love this lace look and it makes a great alternative to a little black dress.

The scalloped hem is super pretty while the neckline is plunging but doesn't reveal too much. If you're on the hunt for something to wear to your work Christmas party then how about trading in your dress for a romper?

The good news is, while it looks fabulous with bare legs, a pair of opaque black tights will look just as chic and you won't catch your death of cold. Always a bonus. Click (right) to buy Hailey's romper now at Revolve or get the look for less with one of the lace lovelies in our edit below.

The birthday girl emerged with a bright orange juice in one hand and a bag of persumably food in the other.

After the big night of celebrations, clearly Hailey was treating herself to a comfy rather than chic day throwing on a pair of loose fit sweat pants and a denim shirt.

It was certainly a different look to her stylish and skin showing lace romper by Alexis she had worn the night before.

Kendall had also wowed on Sunday hitting the award show carpet in a low back mini dress and showing off some new bangs.

On Monday her new haircut was not apparent as it appeared the star had pushed the short sections of hair to either side of her face.

Marking her birthday, Hailey wrote on social media: 'Welp... I'm 19! This has been an interesting year to say the least but it's been so awesome and incredible. I'm grateful for every experience. Crazy how different things are from one year to the next but that's life right?'
