Kylie Jenner has been slammed online after releasing bikinis for kids as part of her new swimwear range.

The beauty mogul, 24, who is reportedly pregnant with her second child, has revealed her upcoming Kylie Swim collection will include swimwear for children in the same colors.

The makeup mogul shared several pieces from the line on her Instagram stories.

It included a bold orange bikini, a pink and red all-in-one swimsuit, and a multi-coloured one-shoulder set.

The mom-of-one simply captioned the snap: "Baby swim!!!"

But social media commenters were appalled by the thought of kids in two pieces.

"Children shouldn't be in bikinis," one person wrote online.

"ALL this family does is strip down and sexualise themselves to sell ANY product, they even sexualise themselves with their other sisters!! and even in photos with their kids!! there's something really wrong with this family," a second added.

"A child in a bikini? That's a no from me," a third commented.

But some people came to Kylie's defense.

"Like her or not. She's smashed it. Billionaire, partner, and now 2 children. Good for her," one person wrote.

"NOT a Kardashian fan, but what is with all the problems with bikinis on little ones? They are so cute! It doesn't sexualize them, they aren't sexual! I loved my little pink bikini in the 70s and I was about 5," a second added.

TMZ reported in 2019 that the Kylie trademarked Kylie Baby.

Fans of the reality star can look forward to goods including strollers, stroller covers, children's car seats, and fitted covers for children's car seats.

The KUWTK star teased the launch of Kylie Baby on part three of her "Inside Kylie Cosmetics" YouTube series last month.
