Dunst ‘weeds’ out rumors at bag-theft trial

The “Mary Jane” ain’t stickin’ to Mary Jane.

“Spider-Man” actress Kirsten Dunst spent an hour on the witness stand as the victim in an otherwise mundane burglary trial yesterday, demurely deflecting questions about her penchant for pot and pricey purses.

The star — who played the semi-arachnid’s true love, Mary Jane, in three superhero movies — was in court because three years ago, her $2,000 Balenciaga handbag was swiped during a movie shoot at the SoHo Grand Hotel.

Asked if she smoked marijuana, she answered with a curt, “No,” but later acknowledged that her assistant smoked pot. She was also asked if she ever advocated its use — which, by numerous news accounts, she has — but was barred from answering by the judge.

James Jimenez — a Brooklyn car mechanic and convicted shoplifter, gun-toter and car thief — is trying to convince a jury that he can’t possibly be a burglar. He says he was merely tagging along with his co-defendant, who he says was the on-location drug dealer at the hotel for the film crew of “How to Lose Friends and Alienate People.”

Jimenez hopes to bolster this defense by reminding jurors as often as possible during the weeklong trial that Dunst’s assistant had a baggie of pot in her own Balenciaga handbag, also stolen. Plus, the shoot was wrapping that night — a milestone Dunst insisted went unheralded.

“We wrapped at 5:30 in the morning and found our bags were stolen and so we all went home,” she testified.

This is the second time Jimenez has gone before a jury with his star-studded case.

Jimenez’s first trial, at which Dunst also testified, ended in mistrial after a single holdout juror believed the suspect was too dumb to realize his co-defendant was casing and robbing the joint as they wandered for an hour through the restricted areas of the hotel.

That time around, in 2009, Dunst hair-flipped and giggled her way through her testimony — chirping, “Hi, how ya doin’?” to the judge before even taking her seat. Yesterday, she rallied — her silvery-blond hair in a prim bob, she deftly doled out mostly yes or no answers to both sides.

Jimenez faces up to 15 years if convicted; he has rejected a two-year prison deal.
