Bella Hadid goes commando in birthday dress

It's her birthday and Bella Hadid's going to give underwear a miss if she wants to.

She's not known for being shy when it comes to sexy fashion choices and the model didn't disappoint when she hit the streets of New York city to celebrate her 21st birthday.

Laced up in a skintight Dolce & Gabbana satin dress that clearly showed she'd left her knickers at home, Bella celebrated with her big sister Gigi and mum Yolanda in tow.

Flaunting it seemed to be the theme of Bella's celebrations, with the model sharing a photo of her wearing a G-string on her Instagram account just hours earlier.

And it seems Bella has her mum's epic booty genes to thank as well.
