Kim Kardashian seems to be in the best shape of her life at the age of 42.

She used to be a size six, but has slimmed down to a size two thanks to her new weight-lifting workouts with her personal trainer Senada Greca.

The reality TV siren looked incredible in a pink string bikini from Chanel as she soaked up the sun during holiday in Turks and Caicos.

The Selfish author had her black hair pulled back and worn in a long braid as she walked into the ocean. Kim looked beautifully made up for her beach day with filled-in brows, pink blush and a mauve lipstick as she flashed light pink nails.

She is enjoying some time off in a gorgeous location after a very busy summer.

The star was in Japan with her daughter North and she was also busy promoting her new SKIMS campaign in August. She also was seen filming her TV show The Kardashians when at Beyonce’s birthday performance in Los Angeles last week.

Turks and Caicos is an archipelago of 40 low-lying coral islands in the Atlantic Ocean, a British Overseas Territory southeast of the Bahamas. Scuba-diving sites include a 14-mile barrier reef on Provo’s north shore.

It has been a weird month for single-mom Kim.

Kardashian is said to be ‘desperately embarrassed and worried’ by her ex-husband Kanye West’s pantless antics.

The Kardashians star has four children with the rapper, 46 – has North, 10, Saint, seven, Chicago, five, and four-year-old Psalm with him – and was married to him from 2014 until 2022.

And she reportedly now thinks something ‘clearly isn’t right’ with him after he was seen with his pants down during a boat ride in Italy with his 28-year-old ‘wife’ Bianca Censori.

A source has said: ‘Kim doesn’t know how she will explain it all to the kids.

‘Kim’s been so worried about the new pics that have come out with Bianca – like how will she explain it all to the kids?

‘She’s embarrassed and worried for him – he’s wandering around barefoot with champagne in the street, something clearly isn’t right.’

Kanye exposed his bare bum to tourists in neighboring boats while riding a river taxi in Venice’s famed canals – while Bianca is regularly seen wearing revealing outfits.

The source added to The Sun: ‘It’s hard for (Kim) because as soon as she thinks she can move on, something like this happens and she’s pulled back into it.

‘It’s like every time Kanye and Bianca pull these nearly-naked stunts, it reminds everyone that Kim dressed up in skintight nude outfits during the marriage. She’d rather put it behind her and forget about it.’

Kim and Kanye have been co-parenting their four kids since their split.

During his bottom-baring outing, Kanye was dressed head-to-toe in his signature black, while Bianca donned a leather trench coat with little to nothing under it.

The pair ‘married’ in a non-legally binding wedding ceremony in January, and were joined by an unidentified female friend. Kanye and Bianca got ‘hitched’ two months after his divorce from Kim was finalized.

Kim – who curated the Dolce and Gabbana Spring 2023 collection inspired by its 90s heyday – recently admitted she still feels like an ‘impostor’.

The businesswoman admitted that the success of SKIMS has made her realize that things have got ‘bigger’ than she could ever have imagined.

She told TIME magazine: ‘Obviously you have big hopes, but this definitely exceeded everything that I ever imagined. I thought it’d be a hit at some Holly­wood party. I still have, like, impostor syndrome or whatever. I think that’s part of what keeps me going.’

The Kardashians star’s shapewear line was inspired by her own struggles with fashion because she had to use household items such as teabags to dye material, so it matched her skin tone.

She added: ‘It started off with simply finding shapewear that was a skin tone that would match my colour.

‘I used to take my shapewear and dye it with tea bags and coffee in the bathtub. I always like to see it on myself. I can absolutely tell when I miss a few drops.’

Kim – who shot to fame when a sex tape of herself and former boyfriend Ray J was leaked onto the internet in 2007 and soon after began starring on Keeping Up with the Kardashians alongside her now-world-famous family – went on to admit that in her next decade, she will ‘not want’ to pose in her underwear.

But the Hidden Hills resident is determined to look as ‘young’ as possible for as long as she can.

She added: ‘I understand that maybe in my 50s, I’m not going to be wanting to pose in my underwear. We’ll do anything we can to look as young as we can and we’re not going to go out not trying.’
