Kylie Jenner shows off her bum in a pink thong bikini as she celebrates pal’s birthday

KYLIE Jenner showed off her bum in a pink thong bikini as she celebrated her pal's birthday yesterday.

The 21-year-old looked incredible as she displayed her enviable curves by the pool at her home in Los Angeles.

The young mum posed for several photos alongside her best friend Stassie - real name Anastasia Karanikolaou - as they wore matching bikinis to celebrate her turning 22.

In one photo, the make-up mogul kneels on a day bed in her living room, as the stunning blonde poses behind her.

Meanwhile, in another snap, the pair can be seen relaxing on a giant inflatable in the star's pool before Stassie falls off.

"It’s ya birthday it’s ya birthday bad b***h contest you in first place,"; Kylie wrote, before jokingly adding: "When the tequila hits."

But the billionairess seemed keen to praise her friend for being loyal for the nine years they'd known each other.

She wrote: "Happy birthday to the baddest @stassiebaby 9 years Iater and you’re still a real one. i love you forever and always."

Kylie also detailed the pair's friendship of nearly a decade on her Instagram story, with several throwback snaps.

She began with their first photo: "So it all started when i met a beautiful bomb ass blonde at Barnes and nobles. This was our first pic together before we were friends."

She continued with a photo of two of them with Kendall, followed by several more photos of their friendship.

She said: "Then soon after you became another sister stas basically lived with me growing up and it was the three of us always. Concerts. We went everywhere on these segways for years before we got our license. Utah trips. Basketball games. More trips."

The Keeping Up With The Kardashian's star then posted a dozen more photos of her and Stassie through the years, including one of her and her beloved daughter Stormi, before posting a short clip as she downed a glass of fizz.

And Kylie ensured that Stassie had a birthday to remember, as she threw her a lavish birthday brunch followed by a chilled pool day with their friends.

As Kylie explained on her Instagram, she and Stassie have been friends for the past nine years, with the stunning model remaining in her life through many trials and tribulations such as the Jordyn Woods and Tristan Thompson cheating scandal.

Jordyn was Kylie's best friend with Jordyn even featuring on parts of Kylie's cosmetic range.

However, Jordyn was snubbed by the star after reportedly cheating on the Kardashian family by kissing Khloe Kardashian's boyfriend and the father of her child, Tristan.

She was forced to leave Kylie’s guest house, where she had been been living, in the aftermath of the drama and moved back in with her mum.

In February, The Sun Online exclusively revealed how Kylie was distraught at losing her closest confidante that her family worried she "won't be able to cope".

An insider explained: "Kylie is devastated about everything. She would never have guessed this would happen. Jordyn is her closest friend and she relies on her so heavily.

"She gets advice on everything from her – Jordyn goes to pretty much every business meeting with Kylie.

"They live together, she helps care for Stormi, she drives her places, she is emotional support when Kylie is overwhelmed."

The source added: "Faced with losing all of that, Kylie is really upset. She's been in tears every day and the whole family is very concerned she won't be able to cope without her.”

While Kylie remained silent following the scandal, she broke her silence on the scandal during an episode of Keeping Up With The Kardashians, which showed the fallout caused by it.

In a clip, Kris Jenner, 63, is heard speaking to Kylie and says: “For you and Jordyn, it’s like a divorce."

Speaking out for the first time about Woods and the scandal, Kylie replies: “She f***ed up.”

She then tells her heartbroken sister: “Just know I love you".

She can then be heard telling someone else: “I look in her eyes, she’s just really going through it."
