Before this adorable girl in her green sweater showed off her singing skills on stage and on the big screen, she looked too cute in her baby photos growing up in London.
She landed her first acting role in a British drama series when she was just 13, but you may also remember that she played Christian Grey's sister in Fifty Shades of Gray – and also sang with her on a film soundtrack Liam Payne for “Fifty Shades Freed.”
Do you need another hint? She rang in the new year Ryan Seacrest!
Can you guess who she is?
