Emma Watson & Daniel Radcliffe spotted on Valentine's Day date

Daniel Radcliffe was spotted on a secret Valentine's Day date with his Harry Potter co-star Emma Watson.

The young celebrities were seen paying a visit to the Imperial Arms in Fulham, West London on February 14th, according to sources.

A source says, 'They arrived quite late at the pub - about 10pm - and sat outside, using each other's bodies for warmth.'

They added that Emma, who wore a black top and pashmina, kept looking around 'nervously' and at one point concealed her face with her scarf.

'The pair seemed totally absorbed in one another's company, though - they were chatting and joking easily until just before closing time,' they continued.
