Alexa Chung, former English model, hosts a daytime talk show on MTV and I must say holds it down, especially with some real awkward guests and interviews; she controls the tempo and definitely alleviates some of the pressure that the guests naturally feel. The show sucks though, but she's hot, her style is hot, and her gangsta makes her hot!

In 2007, Chung came to the attention of the fashion press for her distinctive, quirky style. She frequently appears on Best Dressed Lists, in fashion magazines and on the front row of fashion shows. She socialises with many well-known faces but has said the idea of lots of celebrity friends is "so cheesy". She has dismissed the notion of being an It girl, saying “there’s not much to being an It girl. It’s really quite a depressing title to hold.”
