Alexa Chung, host of new T4 reality TV show Vanity Lair is said to be gaining a reputation as a bit of a diva in telly land, according to The Sun.

A source told the newspaper: “Everyone used to think she was really down to earth. Not anymore.

“On a recent job she acted like some kind of megastar. She shocked the people she was working with by the way she kept turning her nose up at other people’s fashion tastes.”

The insider added: “She should be careful how she treats people. In the fashion industry everyone talks.”
