Gigi Hadid showcases fourth and final collection for Tommy Hilfiger at Milan Fashion Week

After two years, four collections and four big budget fashion shows, Gigi Hadid and Tommy Hilfiger took to the Milan Fashion Week catwalk last night to showcase their final collaborative collection.

Having previously displayed their partnership via a carnival on a New York City pier, a music festival at a Malibu beach and a circus at London's Roundhouse, this season the design duo turned the Milano Congressi into a race track runway.

Entitled 'Drive', the show paid tribute to Hilfiger's love for racing, with models storming the runway clad in black, red and blue leather and cropped tops featuring motorsport motifs.

And, when you're one of the world's most in-demand models, why not enlist your equally in-demand model little sister to walk alongside you?

After walking the show, Bella took to Instagram to share her pride for her sister's blowout showcase.

"I am so beyond proud of the hardworking, kind, talented, smart, funny woman that you are ETCETCETC... (your perfect face being the least of your attributes) congratulations on your 4th and final tommyxgigi collection".

"You exceeded all expectations, not only from me but everyone around you. I am not surprised that you had a another perfect show but yet again, you have surprised me, as you do every day I love you to the moon and back tiny cub."

"Also you're sitting next to me sleeping on the plane like the cutest bear ever and I'm just thinking how lucky I am to have u as a sister!"
