It's Miranda Kerr's 31st birthday today! She's world famous now, but as we all know, Miranda was once a country girl in Gunnedah whose life changed when she won a Dolly model search competition. Since becoming Victoria's Secret's first Australian Angel in 2007, Miranda's modelling career has gone from strength to strength — but she's also had time to run her eco-friendly beauty line KORA Organics, and maintain various fashion and beauty ambassador roles. No matter how well her professional life is going, Miranda always emphasises how her son Flynn is the most important thing in her life — after all, she's a family girl at heart. We're celebrating Miranda's milestone birthday by checking out some of her sweetest and sexiest moments — see them all here. Happy Birthday, Miranda!
