Gigi Hadid

The Vogue cover girl - who has three-year-old daughter Khai with her ex Zayn Malik, 30 - eventually left X (formerly Twitter) after feeling obliged to constantly share details of her private life with her followers.

The 28-year-old model said: "In the very beginning, I was a lot more trustworthy of things, and I feel like I was a lot more freely able to post. You kind of learn that there has to be a difference between how private you wanna be and how private people force you to be. So I try and be as open as I can without revealing too much of a certain situation, but you kind of just have to take it depending on the post and depending where you are."

Gigi still has an Instagram account.
