Kylie Jenner reportedly has her boobs measured every week because she wants to make sure her busty assets are always looking their best.
The 19-year-old reality star - who is rumoured to have undergone three breast operations in the past - is very proud of her assets but monitors them closely to ensure they are always looking their best.
A source told Heat magazine: "Kylie knows they're one of her best assets, so she takes special care of them.
She has them measured every week for any difference in size or sag, and is immediately at her surgeons if there's something out of place."
The 'Keeping Up With the Kardashians' star is said to spend $250,000 a year on keeping her breasts plump and perky.
The source added: "Kylie doesn't care about the cost, she only cares about the results and she's very happy.
"Her breasts are slowly but surely expanding and they look completely natural."
And that's not all as the brunette beauty reportedly spends almost $10,000 a month on laser treatments to keep her skin looking smooth and supple.
The source said: "She has regular laser treatments with her dermatologist to remove stretch marks, veins, or wrinkly tissue...
"The laser treatments are very pricey and something that most people do once every few months.
"But Kylie has it done every week - she spends nearly 10 grand a month."
Kylie has previously admitted she went "too far" with lip fillers.
Speaking to her older half-sister, Kim Kardashian West, she said: "Well, I definitely made my lips a little too big at one point.
"I got excited and felt like I needed to do a lot. And then you guys were like, 'Kylie, you need to chill.'
"And then I had to go back and have it fixed, and it was a crazy process. Thank God I didn't end up on 'Botched'."
