This weekend the A-list were out in force at a host of glamorous red carpet events.

The Audi International Polo event at the Guards Polo club, Windsor, drew the likes of Gemma Arterton and Thandie Newton looking stunning in their racing finery.

Across the pond, this year's Comic Con was in full swing, with Rosario Dawson and Jessica Alba turning up for the photo call for the new Sin City movie.

Rosario kept it simple in a dark green knee-length dress, while Jessica went for the fashion foward approach with a crop top and full skirt look.

At the Entertainment Weekly party, Revenge actress Ashley Madekwe rocked a new season Dior dress and Sophie Tuner (Sansa Stark Game of Thrones) looked gorgeous in a Matthew Williamson black frock.
