Hands up, who hasn't had a weird celebrity crush at one time or another?

Most of us know what it's like to find someone attractive, though for the life of us, we can't think why - but Hilary Clinton's crush has got us baffled.

The US Secretary of State has a thing for David Miliband, Britain's foreign secretary, describing him as "vibrant, vital, attractive and smart."

An interviewer for American Vogue magazine joked about Mrs Clinton having a crush on the 44-year-old British Foreign Secretary after hearing his British accent on the telephone.

"Well, if you saw him it would be a big crush. I mean, he is so vibrant, vital, attractive, smart. He's a really good guy. And he's so young!" said Mrs Clinton, who is 18 years older than Mr Miliband.

And it seems Mr Miliband is equally smitten, describing Mrs Clinton as "delightful to deal with one on one. She's someone who laughs and can tease, and she's got perspective as well."

Hmm, that's one 'special relationship' that sounds pretty cosy to us!
