The Broadchurch star has confessed to getting stuck in her glamourous dress just days before the ceremony.
The embarrassed actress confessed: ‘I tried it on and the zip split and my boob fell out, and then it took two people to get me out of it. They had to cut the zip off. It was a bit embarrassing.’
