Rupert Grint got so drunk at the premiere of ‘Harry Potter and the Half-Blood Prince’ he got into the wrong car the next day.

The 20-year-old actor – who plays Harry’s sidekick Ron Weasley in the boy wizard films – was already anticipating a “big night” when he walked the red carpet in the pouring rain at London’s Leicester Square on Tuesday.

He said: “It’s great to be here. Premieres are always a lot of fun. Always a really big night – if you know what I mean!”

After the event, Rupert and his co-stars Emma Watson and Daniel Radcliffe let their hair down at the after-party.

The next morning, Rupert seemed worse for wear, stumbling out of the exclusive Claridge’s Mayfair hotel looking as though he might be sick at any moment.

The bleary-eyed star was so dazed he got into the wrong car, sitting there for around a minute before he realized his mistake.

The night before, Rupert bragged about his drunken antics at the premiere.

He laughed: “When I’m drunk I like to cause mischief. I’ll steal props like the broomsticks from the ‘Harry Potter’ set and bring them out to the pub for comedy value. It seems funny at the time. Trouble is I usually get too trashed to remember what happened the next day.”

Rupert Grint has recovered from the swine flu after spending a few days in bed – and overcoming some fears.

“It was quite scary when I first found out I had swine flu,” the actor, 20, told reporters at a press conference for Harry Potter and the Half-Blood Prince in London. “I thought, ‘Am I going to die?” added Grint, who plays Ron Weasley in the film. “But it was just like any other flu, really.”

The actor suffered from a sore throat after catching the virus while filming Harry Potter and the Deathly Hallows, but no production days were lost, his rep said.

Harry Potter actor Rupert Grint has contracted swine flu, but is expected to be well enough to attend the London premiere of the new Potter installment on Tuesday, his publicist confirms.

Grint, 20, who stars in the franchise as kid wizard Ron Weasley, called in sick to the set of Harry Potter and the Deathly Hallows — currently filming in London and set for a 2010 release — but has since recovered.

“It has just been confirmed that Rupert Grint has taken a few days out of filming due to a mild bout of swine flu,” his publicist said in a statement Saturday.

“He has now recovered and is looking forward to joining his fellow cast members at the junket and premieres this week and will then return to filming directly afterwards,” she reports, adding that filming was able to continue as scheduled in Grint’s absence.

Harry Potter and the Half-Blood Prince opens in U.S. theaters July 17.
