Alexa Chung: 'I have secret boobs'

Alexa Chung has said that she has "secret boobs".

The model and TV star told Vogue that concerns about the appearance of her collarbone stopped her showing off her chest.

Chung said: "I do have hips. And I do have secret boobs. I do - 32Cs. It's just I have such clavicle issues, I don't like them on show."

Of her earlier days in the modelling industry, Chung added: "God, did I have low self-esteem then. It had always been my mantra, at school, that as soon as I worried about putting on weight, I had to stop [worrying].

"But, you know, you'd overhear an agent and then they'd call you into a room and tell you to tone up. Which, in retrospect, I probably did need to do, but it's not what you want to hear as a teenager and not loving life."

Last November, Chung signed up to host new PBS fashion show Thrift America. Her previous MTV daytime chatshow It's On With Alexa Chung was cancelled in 2009. Chung later claimed that the US did not get her irreverent interviewing style.
