Harry Potter star Ruper Grint has come down with swine flu.

Grint, who plays Harry's sidekick Ron Weasly, is said to be recovering well.

The young star was ordered off filming “Harry Potter and the Deathly Hallows,” amid fears that he could infect the cast and crew.

Grint will rejoin the cast, including Irish actress Evanna Lynch who plays Luna Lovegood, for the premiers of “Harry Potter and the Half- Blood Prince” which opens in New York on July 15.

Grint was the hit of the Belfast festival last year with his performance as Northern Irish teenager Malachy in the indie hit "Cherrybomb."

The film centered on Malachy's battle with another friend for the affections of a girl who drives the friends to dangerous extremes.

Meanwhile, Emma Watson, who plays Hermione in the Harry Potter franchise is expected to move to New York in the fall to attend Columbia University.

Watson says she needs some time away from the Harry Potter circus once "Deathly Hallows" is filmed.

"I’m so excited. Living in London, it’s hard to be anonymous,” she said. “But hopefully, on a campus somewhere, I’ll fade into the background a bit.”

“My whole life has been about Harry Potter and then all of that will shut down and I don’t know what it will be like,” she said.
