Bradley Cooper, Suki Waterhouse Out In London

Cooper accompanied Waterhouse to the Prime Minister’s residence at Whitehall and then headed to Covent Garden for dinner at J Sheekey where they were accompanied by Sienna Miller and her fiancé Tom Sturridge, reported the Daily Mail. For the dinner double date, Waterhouse wore a tee-length black embellished dress, while Cooper donned a similarly all-black ensemble that included slacks, a v-neck sweater and a knee-length trench coat.

Earlier in the day, Waterhouse had walked in, opened and closed the Burberry Prorsum catwalk show at Kensington Gardens for London Fashion Week. While Waterhouse worked the runway in the London brand's Spring/Summer 2015 collection, she was applauded by her friends and fellow models Kate Moss, Cara Delevingne and Poppy Delevingne.

While Waterhouse was the star of the Burberry show, Cooper attended the Tom Ford womenswear show with Vogue editor-in-chief Anna Wintour.

Waterhouse and Cooper have been dating since February 2013 after meeting at the Elle Style Awards.
