A TV Presenter & one of the best-dressers in England. Known to have an eclectic style, being on Vogue's best dressed list, former host of Popworld and most famously being Alex Turner's (of the Arctic Monkeys) girlfriend. Also known to be hated because she is Alex Turner's girlfriend.

Alexa Chung is a 25-year-old, British model-turned-TV host. She started modelling at 16 and became a TV host at 22 when she began co-hosting 'Popworld', along with Alex Zane. Earlier this year she managed to break through to the States when she bagged her own MTV chat show entitled 'It's on with Alexa Chung'. Renowned for eccentric personality she appears to have got ahead by just being herself (who'd thought?).
Billy: Hey, what are you watching?
Bobby: 'It's on with Alexa Chung'.
Billy: Cool. I love this show. Not only is Alexa hot as hell, but she also isn't an irritating fake phony!

3.
Presenter in Britain. Getting alot of fame because of her "great" fashion sense..
which mostly consists of an old check shirt with ridicously skinny jeans and the ugliest boots you ever did see, or a shapeless dress thats more like a mans shirt and wearing mens shoes with brown socks.
She often looks like she just got out of bed.
Do not take style tips from this woman!
Person 1: Omgg check out Alexa Chung's awesoeme shoes! I wonder where she go them from?!
Me: My great great grandad's wardrobe..
