The first full trailer has been released for the third installment of Bridget Jones’s Diary, one day after a short teaser for the film went viral.

Renee Zellweger is back for her title role in Bridget Jones’s Baby, which also sees Colin Firth stepping back into the shoes of Mark Darcy, as well as Patrick Dempsey as a second love interest for the zany singleton.

Singer Ed Sheeran also makes an appearance.

Loosely based on the Bridget Jones’s Diary book series, authored by Helen Fielding, Bridget Jones’s Baby follows Jones in her 40s, ending in a love triangle and debacle over who is the father of her future child.
