Harry Potter star Emma Watson couldn’t be happier about the newfound success of former Hogwarts student Robert Pattinson.

Pattinson — who has become a heartthrob following the success of his starring role as vampire Edward Cullen in the Twilight film franchise — played Cedric Diggory alongside Emma in Harry Potter and the Goblet of Fire and Harry Potter and the Order of the Phoenix.

“[Pattinson] is a super nice guy,” the 19-year-old actress told Entertainment Tonight at the weekend premiere of Harry Potter and The Half-Blood Prince in New York City. “I’m really happy for him that he’s gone on to be so uber successful. It’s really good.”

Emma says of her former co-star’s superstar-level fame, “I hope he’s doing okay. It’s gotta be tough.”
