Discussing friendship being the foundation of a romance, Olivia explained: ‘I think that me and Pete were friends for years. Everyone knows, and we crossed over on various projects. ‘I wouldn’t say we were like particularly close, you know, people say, “Was it weird going from friends to more than?” We weren’t like besties who rang each other every day, so it never had that awkward crossover, but we definitely always clicked. ‘We have the same sense of humour.

Maybe I always thought like “what am I ever going to have in common with a straight man?” ‘And then with Pete it’s like we are friends and we love each other’s company. We laugh, I have as much fun with him as any of my friends, and if he’s joining one of my nights out or vice versa, I don’t feel like I have to change at all.’She added: ‘I think I’ve softened him a little bit.’
