A woman with the "world's smallest waist" has shown off her incredible figure just weeks after giving birth.

Sophia Vegas, 31, has been working hard to get back in pre-pregnancy shape since welcoming her daughter seven weeks ago.

The German reality TV star - whose real name is Sophia Wollersheim - has wowed her Instagram fans with her trim post-baby figure.

She previously claimed to have the "world's tiniest waist" - a look achieved through undergoing plastic surgery, including a bum implant, boob job and having some ribs removed.

In a recent post she showed off her hourglass proportions.

Wearing a black one-piece costume, the new mum could be seen photographed from behind in a swimming pool while on holiday in Cabo San Lucas in Mexico.

Sophia revealed she had lost 14 pounds in pregnancy weight since giving birth.

In another new Instagram post, she could be seen posing beside her partner while on a trip to Canyon Lake Lodge in Canada.

The star showed off her weight loss with a plunging blouse tucked into a red, flared skirt.

Of her fluctuating pre and post-pregnancy weight, Sophia wrote: “I gained a total of 2st (28 lb) and have already lost 1.5st. (21 lb)

“I think that’s a good performance… but somehow I feel the last few pounds are very persistent.”

Her 234k followers have been left impressed by her swift transformation.

One fans wrote: "Wow. I could not look like you seven weeks after the birth of my first child.”

Another commented: "I’m envious you did this in such a short time – pretty woman.”

A third shared: "Omg! How did you do that?”
