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

The young celebrities were seen paying a visit to the Imperial Arms in Fulham, west London, at 22:00 GMT on February 14th, reports the Mirror.

A source reportedly told the newspaper: "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.

Emma and Daniel met seven years ago on the set of HARRY POTTER AND THE PHILOSOPHER'S STONE.

Since then they have co-starred in a further five adaptations of J K ROWLING's novels.

Recently Emma was seen hitting the town with Razorlight front man Johnny Borrell after a London Fashion Week Vanity Fair/Burberry event.

However, the 17-year-old has denied any romantic involvement saying "I only met him at that was all".

Meanwhile, Daniel has recently broken up with his former-girlfriend and Equus co-star LAURA O'TOOLE.

The pair's demanding work schedules were cited as the reason for the split and O'Toole has stressed that they will remain friends.

In other HARRY POTTER news, Daniel has recently rubbished rumors that Steven Spielberg will be directing the seventh and final HARRY POTTER film.

Speaking on the red carpet at the recent BAFTA awards he said that he had no idea where the speculation had arisen from.
