Appearing on This Morning earlier this month, Nicola, who's also known for her work in Spooks, told presenters Holly Willoughby and Phillip Schofield: "It's one of the unexpected gifts of work that you can find great friendship in the workplace and it happened almost immediately with me and Sanj."
She added: "It was like a chemical reaction straight away, we looked each other at the first read-through and we noticed we both had the same look in our eye, which was terror, because it's your first big day of meeting everybody, cautious excitement and terror, and it was exactly the same look. And we both knew from there that we'd be okay."
