Topshop Hits 5th Avenue With A Little Help From Beyoncé & Cara Delevingne

Beyoncé is now officially part of the Topshop crewand that means full-on fabulousness when the brand's bandwagon rolled into Fifth Avenue yesterday. The superstar, who's just been named the highest paid woman in music, arrived at the glittering bash in New York in celebration of the new flagship store and looked suitably sparkly in a sequinned LBD by the high-street chain (buy it at Topshop.com while you still can!)

The bootilicious one was joined by the likes of Naomi Campbell, Julia Restoin Roitfeld, Hailee Steinfeld and Paris Hilton who worked the black carpet to toast the latest addition to Sir Philip Green's empire. They were then treated to performances by Jessie J and Lionel Richie at the swanky after-party.

Bey may have stolen the show, but Topshop shone the spotlight firmly on Cara Delevingne for the magnificent launch. As the face of the brand - and the new Christmas campaign- Cara is THE Toppers girl of the moment and spent the day at the ginormous store, getting a tour from Sir Phil himself. Flights to New York, anyone?
