Stella McCartney's fashion shows always boast a starry front row made up of her A-list pals.
So it was no surprise that a host of Hollywood stars turned out to support her party at London Fashion Week on Sunday night.
Leading ladies Salma Hayek and Drew Barrymore stepped out to cast a discerning eye over Stella's Green Carpet Collection in the capital.

They were joined by fellow A-list actors Samuel L. Jackson and Dakota Johnson, as well as Leonardo DiCaprio's model girlfriend Toni Garrn.
Big names from the music industry were also in attendance, with Rita Ora and Ellie Goulding glamming up for the stylish event.
Colin Firth's wife Livia was also at the helm of the special showcase, which displayed ethical bespoke outfits designed by Stella.

Both Salma and Drew both opted for all-black outfits, as did an unusually low-key Rita Ora, who wore a pinstriped jumpsuit and black sandals. She did, however, add her signature quirky edge to the ensemble with bright pink eyeshadow.
Popstar Ellie, who was showing off her gym-honed pins in tiny leather shorts, was accompanied by her boyfriend Dougie Poynter. The pair looked happy as they posed up together.
Poppy Delevingne and Daisy Lowe represented the fashionista contingent, with Poppy wowing in a full-length green and black striped maxidress. Daisy, meanwhile, wore a one-shouldered monochrome lace jumpsuit.

Speaking of the collection she was displaying, Stella said it was "designed and produced in accordance to the highest sustainability standards.
"For me, it's all one thing, because my business is based on these kind of ethics. It's a very holistic approach for me, it's the way I live my life and it's my message. We're trying to have just a little more conscious consumption."
