She may have risen to fame through her elder siblings, the Kardashian sisters, but Kylie Jenner’s unique and iconic look has been the golden goose that saw her declared the youngest ever self-made billionaire by Forbes in 2020.
Add to that, Kylie, 27, has now been dating tinsel town’s new ‘golden boy’, Timothee Chalamet for two years, with the duo fast becoming Hollywood's new ultimate power couple.
And there’s no doubt that Kylie’s large boobs and curves have transformed the once-shy teen into the ultimate ‘Gen Z’ muse, with fans describing her as ‘the hottest girl in the world’ – a moniker that has earned her millions through collaborations, photo shoots, product endorsements and, of course, Kylie Cosmetics.
But now a source tells us that, as the youngest of the Kardashian clan prepares to turn 30 in two years’ time, Kylie is determined to keep a good thing going and is planning another breast enlargement to boost her business assets and her sizzling chemistry with Timothee, 29, who the insider says loves her ‘Barbie look’.
The source tells us, ‘Kylie loves her OTT look, and Timothee obviously loves it too. He loves that she has enormous boobs and big lips.She’s sharing all these plans with Timothee. He doesn’t have any issue with it. He’s excited and thinks she’s this Barbie doll and he’s reaping the rewards. He is loving every second of their romance and can’t wait to get her home at night!’
They raised plenty of eyebrows when whispers of them dating first emerged back in April 2023, but despite criticism from fans, the unlikely couple appear to have gone from strength to strength.
He’s also said to have moved into the LA mansion Kylie lives in with her two children – Stormi, seven, and Aire, three – and has reportedly splashed out £225,000 on an engagement ring that he picked up in Paris.

We recently reported how their electric chemistry has been a huge factor in their fast-moving romance, with a source telling us, ‘Kylie has bragged about how incredible the sex is and says no one has rocked her world the way Timothee does.’
And last week, Kylie appeared to show Timothee exactly what he was missing as she posted a series of snaps of her in several revealing bikinis as she enjoyed a holiday to the Turks and Caicos Islands with her children and sister Kendall Jenner.
Now the insider says that on her return, Kylie is ready for a summer of love with Timothee, with a new set of boobs to boost their love life.
The insider says, ‘Her boobs are already a 34D, now she’s looking to go up a cup and make it a more voluptuous 34DD. She’s also talking about replenishing the Botox and fillers and butt injections.
‘He’s encouraging Kylie to do more, so it’s not surprising she’s planning a summer nip tuck to keep the spark going and with his full and unconditional approval.'
Despite heavy criticism from fans, who have accused Timothee of ‘having some fun’ with some even cruelly referring to Kylie as an ‘inflated sex doll’, the source says Kylie is determined to have the last laugh.
They tell us, ‘What’s funny to Kylie is that Timothee’s fans are always trashing her online for looking fake and claiming that he’s going to get turned off by all her surgery when the exact opposite is true.
‘He’s constantly telling her how sexy she looks, he’s obsessed with her big bum and huge boobs, he loves the cartoon look she has so it makes her want to push the envelope and do more.
‘She loves how crazy he is for her curves, she’s always dressing to accentuate them when she’s with him and wants to be his ultimate fantasy.’

Romance aside, Kylie is also now estimated to be worth around $710 million, with her cosmetics brand being valued at $1.2 billion. As her brand’s lead ambassador, the source says this ever-present level of high pressure has led Kylie to constantly obsess over her looks.
The insider says, ‘It’s not all for Timothee. Kylie has always been hyper-fixated on her appearance. In her world plastic surgery is as natural as breathing, her and her friends are always talking about what they want to get done next so this would likely be happening with or without Timothee in her life, but still it makes it easier to have his encouragement.’
Kylie previously confirmed she has ‘got [her] breasts done’ before welcoming Stormi with ex Travis Scott in 2018, when she was just 19. And, despite denying she had used any injectables, in 2023, during a brief period of having thinner lips, Kylie told a fan that she ‘got rid of all filler’.
Now, after accidentally displaying the US size 4 on her bikini bottoms in a recent social media snap, our source says Kylie is ‘excited’ that a surgeon has suggested removing fat from her waist and ‘transferring it’ to her bum and boobs.
The insider explains, ‘What’s really exciting for her is that she can do fat transfer to her boobs and butt. Her doctor can take the fat from her thighs and waist and move it to where she wants it to go
‘Plus, she loves having a super small waist and legs so getting them thinned out even more is a win-win as far as she’s concerned.’
However, after previously expressing regret that she had started having surgery as a teen, admitting she would be ‘heartbroken’ if her daughter opted to do the same, the source warns that Kylie, who is naturally beautiful, could further spiral and develop an addiction to plastic surgery.
They say, ‘It’s not just her body that she wants to change, she analyses her face every time she looks in the mirror and sees so-called flaws that need fixing. She’s not even 30 but she worries a lot about being ‘old’ and is convinced that all these procedures will mean she stays looking young forever.
‘It’s such an unhealthy attitude and it’s sad that Kylie feels she needs to keep adding more to her surgery 'shopping list'.’
