Blockbuster film franchises Harry Potter and Twilight have a new romantic link if reports Bonnie Wright is dating Jamie Campbell Bower are to be believed.

The couple was recently spotted attending an event at London's Saatchi Gallery together and onlookers felt sure the Harry Potter star and the movie vampire were an item.

One tells WENN, "They seemed very close, very intimate. They were definitely together."

Wright, who was briefly linked to Zac Efron in 2008, has admitted to being a Twilight fan, hinting that the film's lead hunk, Robert Pattinson, isn't her personal pin-up.

She recently said, "I can't deny the fact that he (Pattinson) is cute, but he is not my type."
