Kylie Jenner shows off her curves and famous butt in a sexy cutout dress as she thanks loved ones for “birthday wishes”.

KYLIE Jenner was pictured on a yacht to celebrate her 26th birthday.

The Kardashian sister shared one series of photos on her Instagram feed from her big celebration.

Kylie wore a skintight black dress that hit her above the knees but showed off her famous butt.

The dress featured several oval cutouts at the lower back and her upper back was completely exposed.

Her hair was pulled back in a bun and her face was full of glamor for the photoshoot.

The Hulu personality leaned on a glass handrail on the edge of the luxury yacht.

When she wasn’t looking over her shoulder at the camera, she was looking out to sea.

The Kardashians star captioned the post, “Thank you for the birthday wishes. Forever grateful.”

YACHTS AROUND

Fans of the reality TV show discussed Kylie’s post on Reddit and don’t understand the appeal of yachts.

One said: “Do you think any of them ever like…funny things? Just don’t know how? Being rich just seems so boring to watch them.”

Another fan replied: “They fly their private jets to the most beautiful places just to take pictures. It’s so depressing.”

A third said: “Yachting and showing off that LongBottom.”

Someone else said, “Oh, she spent her birthday sailing with a friend. This is something else.”

Before posting her photos on the yacht, Kylie flaunted her body in a tiny thong bikini and a set of birthday thirst traps.

The Kylie Cosmetics founder nearly burst out of her tiny black bikini when she was photographed spending time on a tropical beach.

A shot on the carousel showed Kylie sitting right on the shore and seemingly looking up at the sky with gratitude.

Showing her butt, the TV star sat on the sand in a thong bikini enjoying the clear blue water.

Other shots in the post included a window shot from her private jet, a turtle swimming in the water, and a few day and night shots of the beach.

In her caption, the mother-of-two simply wrote the number “26”, accompanied by prayer, flower and balloon emojis.
