Mrs. Markowitz swag-gers her way around town:

Who knew the first lady of Brooklyn was also its biggest booster?

Jamie Markowitz, the wife of Brooklyn Borough President Marty Markowitz, scooped up eight pricey fiberglass place mats - works of art by pop artist Takashi Murakami - set aside for guests at a glitzy Brooklyn Museum gala.

The limited-edition Technicolor mats, which have sold for $1,000 on eBay after a similar event, were included in a grab bag of pricey freebies for guests celebrating the opening of the artist’s three-month exhibition last Thursday.

“It’s a little true,” Markowitz laughed Sunday when asked about an item on RadarOnline.com that painted her as a tad greedy.

Radar reported that when several guests who didn’t get a mat asked for one of her eight, she replied, “You guys really should have acted faster. This is Brooklyn!”

To another, she said, “You snooze, you lose, buddy. Forget it.”
