Taylor Swift stepped out in a very stylish black floral frock while out in London on Thursday night, celebrating pal Poppy Delevingne’s 40th birthday.

The pop megastar was among names including Georgia May Jagger, Lily James and Cara Delevingne who headed to the famous Hart pub in London, before celebrations continued with an after party at 77 at the luxury BoTree hotel in Marylebone.

But Taylor made sure to dress to impress in a £1,575 Zimmermann chic floral corset midi dress and black £695 Jimmy Choo heels, as she walked hand-in-hand with NFL fiancé Travis Kelce.
