British actress Emma Watson has left her Harry Potter co-stars red-faced - after beating them at ping pong. The 17-year-old - who plays Hermione Granger in the boy wizard franchise - has left stars on the set of Harry Potter And The Half Blood Prince too terrified to challenge her to a game.

Rupert Grint - who plays Ron Weasley - says, "I've got a table tennis on set and we're always playing between scenes.

"Dan (Radcliffe) has been have a few lucky months and we've both been getting really good but Emma is brilliant. We rarely play her now because it gets quite embarrassing."
