KEY POINTS:
Daniel Radcliffe spent Valentine's Day 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.
Meanwhile, Emma Watson's parents have banned her from seeing Johnny Borrell, it has been claimed.
The star's mother and father "went mad" after finding out their 17-year-old daughter had been partying with the Razorlight frontman last week, and have now forbidden the pair meeting again.
A source close to the family told Britain's Daily Mail newspaper: "They told Emma in no uncertain terms that she's not to see Johnny again.
"They have always kept a strict eye on their daughter and are very protective parents.
"It was a huge shock to see their little girl coming out of a party with hell raiser Johnny on her arm. He's 10 years older than her and he's admitted to being a drug addict in the past."
Emma - who plays schoolgirl Hermione Granger in the hit movie franchise about a teen wizard - and Johnny, 27, were spotted together at London's National Portrait Gallery last Monday before partying at nearby nightclub Dolce.
However, Emma insisted there was nothing going on.
She said: "At London Fashion Week I met Johnny Borrell and we went on to a party hosted by designers PPQ in the same cab. I'd never met him before so that was great as I'm a big Razorlight fan.
"But goodness, I am really going to have to watch who I stand next to from now on!"
