The young actress, who plays Hermione in the movie series, not so long ago moaned that her fame was having a negative effect on her love life, has reportedly fallen under the spell of Tom Ducker, a 17-year old rugby player.

And so enamoured are the two with each other that they even enjoyed a romantic getaway on the French Riviera recently.

Watson, 17, and Ducker were spotted hanging out in nightclubs and eating lobster with champagne while they stayed at Chateau de la Chevre d'Or in Eze, near Nice.

Staff at the swanky Chateau, where suites with ocean views cost 385 pounds a night, said that the two teens were 'delightful guests'.

"They arrived quietly at about 7.30pm and drank champagne and ate lobsters all night. They were clearly loving each other's company and said they were in a very romantic place, with the Mediterranean just in front of them and great music," the Daily Mail quoted owner Ali Abdelhafidh, as saying. "They said they were having a wonderful holiday and did not leave until well after 2am. It was great to see a young couple so much in love but Emma had time for everyone else, too.

"A lot of celebrities come here, including Elton John and Bono, but having Emma here was something special. She's a real star in every sense of the word."

A fellow diner said: "They were knocking back the champagne and didn't stop laughing and joking. Emma was acting like a beautifully mannered young woman. Castel Plage is very sophisticated and the two of them looked in their element."

However, Ducker's father John insisted that there was nothing romantic between them, and that they were simply friends.

"They are just friends - don't read anything more into it than that. My wife and I have met Emma once or twice. She is a lovely young lady," he said.
