Has Bella Hadid had plastic surgery? The globe-trotting model says it's not possible — she's afraid of any related procedures.

Hadid opens up about being on the receiving end of tabloid gossip in a new interview with InStyle, and challenges anyone who says she's lying about surgery to put her to the test.

"People think I got all this surgery or did this or that. And you know what? We can do a scan of my face, darling," she says. "I'm scared of putting fillers into my lips. I wouldn't want to mess up my face."

And while Hadid has become one of the world's most famous models, she says her career was born out of tremendous physical insecurities.

"People think I'm very confident, but I really had to learn how to be," she says. "I had a small waist and big hips and was kind of chubby. I love them now, but I was always self-conscious of my hips -- whereas my sister [Gigi Hadid] had a six-pack and was very athletic. And I thought I had such a weird face. I remember very distinctly getting bullied because of my features."

"I've gone through a lot of phases," she adds. "When I was 16, I really wanted to make a point of whatever it was I was trying to do, so I had grills before it was cool — I was definitely not cool — and I dyed my hair blue with pink underneath. I had rainbow hair at one point too. It was hysterical. In terms of makeup, I really didn’t know how to do anything on my face until I started working with Dior and Peter Philips. I had no idea how to blend or how to do my brows. I look back like, 'Wow girl, you've really learned.'"
