SUPERMODEL sisters Gigi and Bella Hadid strut their stuff as they lead a pack of famous clothes horses modelling for Milan Fashion Week's Alberta Ferretti catwalk show.

Bella, who used to date The Weeknd, looked amazing in a strappy black bikini and matching jacket while her older sister was given a halterneck swimsuit.
Later the pair changed into metallic dresses and tie-up shirts for the catwalk bonanza, which saw the models
Alec Baldwin's daughter Hailey, 20 - a former flame of Justin Bieber - joined the modelling crew in a sexy bandeau dress and matching heels.
Meanwhile veteran model Alessandra Ambrosio, 39, turned up to model a stunning black strapless dress.
Also hitting the runway was Barbara Palvin, 23, who was spotted sneaking out of a flat where she'd been partying with footie star Neymar earlier this week.
The gorgeous Brazilian, who was introduced to the athlete by mutual pal Lewis Hamilton, looked stunning as she worked her tailored look.
Other models showing off designs in the Italian venue were Elsa Hosk, Shanina Shaik, Joan Smalls and Isabeli Fontana.
The revealing outfits went down a storm with the applauding crowds, and Gigi didn't put a foot wrong - despite stumbling during her previous Milan catwalk in February.
