Keira Knightley, mum to Edie - born May 2015
Keira and husband James Righton tend to keep their private life out of the spotlight, however, the actress did open up about motherhood in one interview last year, saying she is head over heels in love with her little girl.
"The love is astonishing," she said. "It's a very primal, primal love. That's quite extraordinary. And the ability to have no sleep and continue going. It's not pleasant – I never thought that I could actually do it for the amount of time that I've done it." A lot of new parents can probably relate to that feeling!"
