Renee Zellweger, Hugh Grant and Chiwetel Ejiofor were among the stars on the red carpet for the premiere of Bridget Jones: Mad About the Boy in London‘s Leicester Square.

The film is the fourth instalment in the franchise, which takes its title from the latest Bridget Jones novel, which was published in 2013.

In the latest instalment, Bridget – now a 51-year-old widow and single parent – grapples with texts, tweets, dating apps and Botox after the death of her husband, Mark Darcy.
