The Texas native has been working hard on her British accent and she's convinced people will think she actually is the wife of Prince William.
She tells WENN, ""I'm going as Kate Middleton. I've got the blue dress and the tiara and the British accent so I'm pretty excited.""
But her 2012 Halloween outfit has got nothing on the one her grandmother made her as a child: ""I was pretty traditional as a kid. My grandmother made me a princess costume when I was very young. It was pink with lace and little rosebuds on it. It was beautiful and I still have it in a box somewhere.
""That was a pretty amazing handmade costume so it would have to be my favourite of them all.""
