Kim Kardashian and her sister Kourtney were basically twins as they matched in blue swimwear for a new post.
Kourtney turned 43 years old on April 18 and her younger sister took to her Instagram page to pay tribute to her.
The SKIMS founder shared a couple of photos of the two sisters posing in bright blue swimwear at the beach.
"Each year around the sun with you I learn and grow and evolve more because of you!" the 41-year-old wrote.
"Thank you for teaching me to always go for it and follow my heart even if no one else understands.

"They just aren’t on our growth path lol Happy Birthday @kourtneykardash! Happiness looks so good on you. I love you so much!!!"
In one of the snaps, Kim and Kourtney fake dove into the water whereas, in one picture, the duo simply stood on the sandy beach and posed.
Fans took to the comment section to post heart eye emojis, fire emojis, and birthday messages to the eldest Kardashian.
Kourtney kicked off her birthday celebrations over the Easter weekend with her beau Travis Barker.
On her InstaStories, the mum-of-three shared a video of her cutting a black cake shaped like Mickey Mouse with her name written on it in yellow sprinkles.
When the cake was cut open, it released a mountain of black, red and white sprinkles

Kourtney wrote in an accompanying caption: "Yummmm and yes I know I forgot the plate in the last slide."
She also shared a photo of a stunning bouquet of pale pink and cream roses from her rocker other half.
The star later posted a snap of Travis slipping a shoe on her foot, in a call back to the Cinderella fairy tale.

The reality star tied the knot with her fiancé following the Grammys in Las Vegas, but later confirmed it wasn't an official wedding as the pair were just 'practising' for the real thing.
In an interview on The One Show with her sisters Khloe and Kim, she chatted with Rylan Clark about the wedding, describing it as a "wild Vegas night".
Asked about the big day, Kourtney said: "It was fun, Elvis sang when I walked down the aisle," as Khloe revealed the manager of the Elvis impersonator got her to speak to him via FaceTime.
