Kendall Jenner flashes her underboob as she celebrates her birthday in casual style with sisters Kim and Kourtney, mum Kris and pal Hailey Baldwin

KENDALL Jenner revealed a glimpse of underboob as she celebrated her birthday last night.

The star, who has just turned 22, looked amazing in a white crop top and jeans, teamed with a pair of sparkly knee-high boots.

It was an unusually low-key bash for the model who was joined by her nearest and dearest for dinner at Petite Taqueria.

And she showed things are going very well with boyfriend Blake Griffin as he joined the family members for the special occasion.

Kim Kardashian hot footed her way there following her appearance on Jimmy Kimmel Live! and was joined by her husband Kanye West.

Momager Kris attended, alongside boyfriend Corey Gamble, while Kourtney was there with her boyfriend Younes Bendjima.

Showing off her great sense of style, mum-of-three Kourt wore a pair of flared trousers with a crop top.

Kylie and Khloe, both of whom are reportedly pregnant, were noticeably absent from the intimate dinner.

But what Kendall was lacking her sisters, she made up for with her best pal Hailey Baldwin.

Caitlyn Jenner also made an appearance for the sake of her daughter, despite her recent estrangement from the family.

The model, who is the daughter of Stephen Baldwin, looked great dressed in a black minidress, with her hair styled in Hollywood style curls.

Model Kendall has been dating basketball played Blake for a few months and the couple are thought to have recently become serious about each other.

A source told Us Weekly recently: "They're legit. They're a full-on couple.

"Kendall has been going to a lot of his games and they have been enjoying time at home when Blake is in town. They're good."

Blake, 28, is a father of two who was previously engaged before meeting the Keeping Up With The Kardashian’s star.

The outing comes after Kendall’s sister Khloe revealed that the model was just as much a victim of body shaming as she was.

Khloe shared: "But just because you're thin - there's still bullying and body shaming with skinny girls. That's how Kendall was all the time.

"I think people like to say, oh you're not plus size so you don't have a problem. But it's both ends of the spectrum, and thats what were really trying to just stop. It goes so much deeper, it affects how you are in public, how you conduct yourself going into interviews, any of that."
