Hilary Duff has been working that cute girl-next-door charm of hers for years now. Years, I tells ya. But did you know that she's a mad hair accessories fan? It was pink bling way back when, then headbands, now it's anything that holds a braid in place. She's also been known to mix up her colour and style, going brunette then black and experimenting with balayage and bangs before realising that she's best working her signature blonde locks. Check it all out as we wish mum-to-be Hilary a very happy 24th birthday!
