London was calling, and Alexa Chung, Keira Knightley [1], and Cara Delevingne were more than happy to reply. The ladies were joined by a flock of stylish stars for the annual Serpentine Gallery Summer Party — and they weren't the only ones making the trip across the pond. Model of the moment Irina Shayk bared her gams in an LBD at the UK photocall for Hercules, while Keira returned to the city again later in the week for a Begin Again photocall.
Another actress who has us crushing hard this week is someone new to our hearts: Transformers star Nicola Peltz [2]. With a handful of stylish premiere looks down, the actress continues to blow us away — and a duo of sleek, white dresses in Berlin was no exception. See her and all the lovely ladies who had us falling hard this week.
