Bella Hadid has one of the most stunning faces in the modeling business.

But six years ago the sister of Balmain spokesperson Gigi Hadid, 20, didn't quite look the same, with a rounder nose and thinner lips.

And this week, Star magazine is reporting the girlfriend of The Weeknd had some help getting those perfect features.

'Bella has always been hugely insecure,' a friend told the publication. 'But it really ramped up when Gigi started modeling.'

The magazine suggested she went to see a doctor about it: 'She really went to town with her dad's credit card and is practically unrecognizable.'

The source did not make clear what she had done, whether it was just fillers or something more.

Her father is developer Mohamed Hadid and mother is former model Yolanda Foster, both of whom have appeared on hit bravo reality series The Real Housewives Of Beverly Hills.

Whether Bella has had work done or not, one thing is for certain: she is now considered one of the top models in the fashion business.

The former equestrian got her start modeling in Elle magazine, which led to runway shows for Diane Von Furstenberg and Balmain.

She was also front and center with her 26-year-old singer boyfriend The Weeknd, real name Abęl Makkonen Tesfaye, at last month's Grammys.

She has often been compared to sister Gigi, which she said has presented some challenges.

In October she told Seventeen: 'I just have to remind myself that she's been doing this forever. I can't keep comparing myself to her because we're so different. But people still love to compare and contrast us - what's better about her or what's not that good about me - and it's hard because people are really mean.

'But I'm her biggest supporter, and she's my biggest supporter. We're not competitive at all.'

Bella also has a 16-year-old brother, Anwar, from her mother and father's six year marriage, which ended in divorce in 2000.

On Tuesday her mother Yolanda told Dr Oz that Bella's battle with Lyme disease dashed her Olympic hopes.

'Every night, she would [say],'Mommy, massage my back please, and I would make hot baths, and salt baths and try to massage her but from there, it went into her brain,' she said.

And then she could not compete.

'Bella wanted to be a professional horseback rider, and her dream was to go to the Olympics. She's been on a horse every day of her life since she was two years old. And all of a sudden she jumped 4-foot-5 courses and you need to have a very sharp brain in order to do the calculations. And she started making mistakes.

'All of a sudden instead of a six stride, she was trying to do it in a four stride or a seven stride and big accidents started happening,' she added.

Both Bella and her brother, Anwar were both diagnosed with Lyme disease in early 2012.
