Hot on the heels of her denial over report that claimed she dated Razorlight notorious rocker Johnny Borrell, Emma Watson has fueled another dating rumor as she's been spotted spending Valentine's Day together with her "Harry Potter" co-star Daniel Radcliffe. Rumor has it that the actors were seen going on a secret Valentine's Day date together.

Per the Mirror, Emma was spotted huddling together with Daniel in the garden of the Imperial Arms pub in Fulham, West London with an onlooker claimed Emma appeared to have totally fallen under Daniel's spell. The pair were later that evening seen hugging and laughing.

"They arrived quite late at the pub - about 10pm - and sat outside, using each other's bodies for warmth," the witness said. "Emma, who was wearing a black top and matching pashmina, kept looking over her shoulder nervously as if she didn't wanted to be recognized. When people started to notice the couple and began pointing, she wrapped her scarf around her head so only her eyes were peeping out."

As of Daniel, the promising actor was said to find Emma's "new look hysterical and started laughing. Throughout the night, in fact, he just kept giggling like a love-struck teen."

Both Emma and Daniel "seemed totally absorbed in one another's company, though - they were chatting and joking easily until just before closing time," the source added. "They then left the pub, heads together and whispering, and headed in the direction of Daniel's home nearby."

Daniel was said to have split from rumored girlfriend Laura O'Toole. Neither of them have ever confirmed any dating or split rumors though.

Daniel and Laura were co-stars in Peter Shaffer's 1973 play "Equus". Laura was known as the understudy for the lead female character of Jill, played by Joanna Christie, who engaged in a lengthy nude sex scene with Daniel's character in the play.
