I guess they forgot to teach the spell that would repel the swine flu at Hogwarts, because NineMSN is reporting that Harry Potter star Rupert Grint has come down with the virus.

It was only a matter of time before a celebrity came down with swine flu, and Harry Potter star Rupert Grint is the unlucky first.

The 20-year-old is under quarantine after contracting the virus and has had to take time off from filming Harry Potter and the Deathly Hallows.

His publicist confirms, “Rupert Grint has taken a few days out of filming due to a mild bout of swine flu.”

Luckily Rupert hasn’t been affected too badly by the virus — which has killed 332 people worldwide — and he’s expected to be on his feet again to join his castmates at the London premiere of Harry Potter and the Half-Blood Prince tomorrow.

Since he’s a celebrity and can get into places I can’t, maybe he’ll go cough on the cast of Twilight for me.
