NEW YORK, USA - Talk about Washington and London's special relationship.

US Secretary of State Hillary Clinton has admitted she has a 'crush' on Britain's youthful-looking, 44-year-old foreign minister David Miliband, according to an interview published in US Vogue magazine.

'Oh my God!' she was quoted as telling a Vogue journalist in the December issue. 'If you saw him it would be a big crush.'

Clinton, who is married to former US president Bill Clinton, described Miliband as 'vibrant, vital, attractive, smart. He's a really good guy - and he is so young!'

According to Britain's Sun daily, Miliband reciprocated the gushing feelings, calling Clinton, 62, 'delightful' and a 'tease.'
