Gigi's Waisting Away!

Concerns grow as the model continues to shrink

Gigi Hadid insists that her ever diminishing size is due to her battle with the thyroid condition Hashimoto’s disease.

“If I could choose, I would have my ass back and I would have the tits I had a few years ago,” she tells pal Blake Lively in a new interview for US Harper’s Bazaar’s May issue. “But we can’t look back with regret. I loved my body then, and I love my body now.”

But as the model continues to become a shadow of her former curvaceous self, her nearest and dearest are worried something more sinister could be causing her drastic weight loss.
