She is rumoured to be five months pregnant with her first child with rapper boyfriend Travis Scott.

But Kylie Jenner had business on her mind on Wednesday, as she shared throwback snaps on Instagram from her second collaboration with sunglᴀsses brand Quay Australia.

In pH๏τos taken before her reported pregnancy, the reality star, 20, showcased her incredible flat stomach in a skimpy white crop top, before going braless as she posed in a purple fur jacket.

In other snapsH๏τs, the cosmetics entrepreneur showed off the new eye-wear while wearing a white tank top.

Another of her outfits – matching a boxy pair of white-rimmed shades – featured a slightly sheer, flowing white top she’d let slide off her left shoulder.

While posing in a sleeveless black top and canary yellow shades, she looked a ᴅᴇᴀᴅ ringer for her mother-of-two half-sister Kim Kardashian, 36.

Kylie’s baby news emerged earlier this month, with it subsequently claimed she fell pregnant after just two months of dating rapper Travis Scott, 25.

Kylie is believed to be expecting a baby girl at around the same time as sister Kim welcomes a girl via a surrogate with her rapper husband Kanye West, 40.

In another family bombshell, it was revealed earlier this week that Khloe Kardashian, 33, is pregnant with her first child with basketball player beau Tristan Thompson, 26.

It’s emerged that Kylie was leaning on Kim and the girls’ ‘momager’ mother Kris Jenner, 61, in the wake of her discovery.

A source told Us Weekly: ‘They talked through her decision-making process regarding moving forward with this pregnancy, having the baby and what she’s going to do.

‘Kris is so supportive and she knew this was a Kylie decision. They all wanted Kylie to make the decision for herself and to understand this is what it looks like, this is how your life will change, and Kylie gets that.’

It’s at odds with a People source last weekend, who claimed the family ‘think Kylie is too young to have a baby’.

The insider said: ‘Whenever things were good [with ex Tyga], Kylie said she wanted a baby. Between spending lots of time with her nieces and nephews, and being around Tyga’s son, she claimed she was ready.

‘Her family would beg her to protect herself. They were very concerned.’

Kourtney Kardashian, 38, is mother to three children, son Mason, seven, daughter Penelope, five, and son Reign, two, with ex-boyfriend Scott Disick, 34.

Kim raises daughter North, four, and son Saint, 21 months, with Kanye.

Rob Kardashian, 30, is a father to baby daughter Dream, 10 months, with former fiance Blac Chyna, 29.

Kendall Jenner, 21, is the only member of the Kardashian family who is not a parent or doesn’t have a baby in her immediate future.

Kylie, Khloe and Kim have all remained тιԍнт-lipped on their baby news and none of the sisters have publicly confirmed or denied the claims.
