Kim Kardashian's plastic surgery timeline in full as star exposes her 'injected bum' in tiny bikini

With the recent pictures of Kim Kardashian partying in Mexico doing the rounds, eyebrows have been raised over the star's figure.

Looking as slim as ever in a vintage Dior bikini - and with tape placed deliberately over her nipples to prevent any errant wardrobe malfunctions - Kim was body-confident as can be after giving birth to her second child, Saint 16 months ago.

But many were left wondering what Kim had done to her face and body in the decade or so since she's been in the public eye - especially as her trademark behind looked bigger than ever.

Here's a rundown of all the rumoured plastic surgery and procedures Kim is believed to have had over the years. Kim Kardashian Killer Curve Put On Display As She Steps Out In Los Angeles

So how did Kim get her famous bum?

Kim has long denied having bum implants to enhance her famous butt. She even submitted to an X-ray in Season 6 of Keeping Up With The Kardashians to silence the critics who insisted she must have had implants put in to explain the rapid inflation of her bum from before she was properly famous.

But, as a surgeon from MYA.co.uk points out, there were other ways to boost Kim's bum that didn't involve silicone implants.

"This does not rule out fat transfer/fat injections to the buttocks. This would not show on an x-ray as it is the patients' own body fat and not an implant," the spokesperson pointed out.

"It is possible she has had fat transferred from less desirable areas such as the waist or stomach and had it put into her buttocks and hips to create a curvier frame."

This is known as the Brazilian bum lift and costs in the region of £5-7,000.

The suspected nose job

Having once admitted her nose was her biggest insecurity, Kim has always denied having rhinoplasty on it.

As she revealed to Wonderland magazine in 2016: "People think I've had my nose done. I haven't.

"I used to hate this bump on my nose. Hated it. Now I love that it makes me look more ethnic."

However, Kim did admit that she could see why people thought she'd had work done on it, saying: "It does look smaller. Maybe it's the contour I use."

The MYA expert reckons the difference is most noticeable when looking at older pictures of Kim compared to now. They say: "She has most likely had an open septo rhinoplasty to slim the bridge and an alar base reduction to refine the tip of the nose.

"Scarring is minimal and recovery time is roughly around 6 weeks but it can take up to a year for the swelling to fully settle."

The estimated cost of such an operation is between £6,000 and £10,000.

The boob job(s)

Pictures of Kim from before she became properly famous – AKA the Paris Hilton wardrobe assistant years – show a young woman who, while in no way flat-chested, was definitely not blessed with the cup size of her later years.

The MYA surgeon tells us: "In my professional opinion, based on the images I have been shown, I would suggest that Kim has under gone a breast enlargement during KUWTK Season 1 to 4.

"There appears to be more fullness to her breasts whilst still staying in proportion to her frame; she has clearly asked for a natural breast enlargement."
