Daniel Radcliffe spent Valentine's Day (14.02.08) with his 'Harry Potter' co-star Emma Watson.

Daniel, who stars as the boy wizard in the hit movie franchise, took Emma to west London's Imperial Arms pub where they spent the evening hugging and laughing.

A source said: "Everyone thought it was amazing they had decided to spend Valentine's Day together - the most romantic day of the year. They looked like a love-struck couple who only seemed to have eyes for each other.

"Daniel and Emma arrived quite late at the pub - about 10pm - and sat outside. They used each other's bodies for warmth."

Emma - who has reportedly been banned from seeing Razorlight rocker Johnny Borrell after the pair partied together last week - was keen to keep her blossoming romance with Daniel, 18, a secret and hid her face with her scarf.

The source added to Britain's Daily Mirror newspaper: "Emma kept looking over her shoulder, she didn't want to be recognised. When people began to notice the couple, she wrapped her scarf around her head so only her eyes were peeping out. Daniel found her new look hysterical and started laughing. He spent the evening giggling like a love-struck teen."

Daniel, who split from his 'Equus' co-star Laura O'Toole last year, has known 17-year-old Emma since the pair met on the set of 2001's 'Harry Potter and the Philosopher's Stone'.
