Kourtney Kardashian puts her bottom on display in Mexico

Kourtney Kardashian is in the best shape of her life and she wants everyone to know it.

The eldest Kardashian, 38, showed a photo of her backside on Wednesday while in Punta Mita, Mexico with her beau Younes Bendjima, 24.

The reality TV star had on only a skimpy bikini as she dug into her guacamole with chips.

This comes days after the two were spotted at the airport on Sunday.

She had none of her three kids - Mason, Penelope and Reign - in tow.  

The two have been on several trips together during their one year relationship, including NYC, Paris and Egypt. 

In an Instagram snap shared Tuesday, the Keeping Up With The Kardashians star was wearing a white bikini with white sunglasses while in a swimming pool.

The looker was toned and tanned in the snap as she had one foot in the pool and the other on the border.

Below her was the beach and to the side Bougainvillea plants in full bloom.

There are more images on Snapchat. Kourtney is seen in a black bikini as she has a meal on the beach.

Younes went shirtless, briefly showing off her chiseled figure while relaxing with his love in the sun.

The duo were spotted reclining on beach chairs together at their luxury digs.

Kourtney leaned to look at something on Younes' phone, craning her neck over the tall, handsome model's shoulder to get a peek at the screen.

There, the eldest Kardashian covered up in a white button up while her other half wore a similar olive style. 

Arriving at an airport in Puerto Vallarta, the couple was dressed down.

Kourtney wore a black top with track pants and sunglasses.

Besides her, Younes had on olive green while he carried a bag emblazoned with the letters 'KOURT.'

The couple were similarly understated for their flight back home on Tuesday.

Mother-of-three Kourtney looked comfortable in light-washed denim and a plain black pullover.

Her raven locks looked ultra shiny, styled straight and sleek.

She toted a customized bag at her side while Younes rolled two suitcases through the terminal.

The Algerian talent sported the same faded green sweatshirt he wore during his travels South of the border. 

He donned a pair of coveted Yeezy Wave Runner 700 sneakers on foot while his love wore classic white kicks. 

The couple's getaway comes on the heels of the siren's brand new campaign for Calvin Klein lingerie, which she shot with her siblings Khloe, Kim, Kylie and Kendall.

Kim looked toned and incredible, though some haters said she looked like an 'alien' due to being Photoshopped.

She wore both black and white bras and panties. 

Khloe, who is pregnant with her first child, appeared to have no bump. She is over six months along and the father is Tristan Thompson.

And Kylie, who is also with child, went to great lengths to hide her midsection. She is expecting her first baby with rapper Travis Scott.

Kendall, a Vogue model, was also present.

The Calabasas native was also seen on Sunday's episode of KUWTK complaining about ex Scott Disick, 34.

He had called her at 2am to talk about life and how she finally and bluntly told him that model Bendjima, 24, was her serious boyfriend.

Kourtney told her sisters that the next day she had rushed over to see Scott because he was behaving erratically.

But when she got there he acted 'aggressively' toward her and she sat him down for a serious talk about their family's future.

The drama unfolded as Kourtney told Khloe about the phone call from Scott.

'Last night Scott called me at like 2am, he never calls me late at night ever. He was just ranting like ''What are we doing in life? What am I doing What are you doing?''

'I will go ''But what are you doing?'' or then he will say ''But what are you doing? Is it any better?''

'By the end of the conversation I was just like ''I have a boyfriend and he is 24-years-old, it's not the craziest thing that has ever happened in the world.

'And he was like ''He is your boyfriend?'' and then he hung up the phone,' Kourtney said.

Khloe asked her if she had tried to call him back.

'No, I just went to bed,' said Kourtney smiling.

'Cut The. Cord,' said Khloe.

Got to do what you have to do. I just thought he knew. I thought how could he not know, we have been to St Tropez and Egypt together. What does he think that I just go on these elaborate trips?'

Khloe told her that Scott - or the rest of the family - would not have assumed anything.

'I thought it was a guy you were dating. Why would we assume anything unless we hear it from you, you cannot assume people know,' said Khloe.

Khloe told the cameras that she was proud of Kourtney for opening up to Scott about her relationship.
