The "Begin Again" star, who has five-year-old daughter Edie with husband James Righton, had previously rejected the lead role in the Broadway show "Therese Raquin" but since giving birth to her little girl, she is not worried about failing anymore, reported Female First.
"I think motherhood puts everything into perspective, I really do. I've been offered (the Therese Raquin part) a bunch of times and I've always gone, 'Well, this is scary and this is really difficult'.
"I still find it terrifying, but why not give it a go. I'm very grateful to become a mother while doing something this unbelievably difficult, because honestly the worst that could happen is that you fail."
"You try your best and I've been really lucky that I have had the opportunity to be working and finding interesting things, and working with interesting people while being a mum at the same time.
"Ultimately as long as my kid is alright, everything is fine," she said.
