Madonna had an intimate dinner in Brooklyn with boy toy Brahim Zaibat this week. Spies saw Zaibat cooling his heels Wednesday at Antica Pesa in Williamsburg, waiting for the Material Girl to show. Madge later arrived in a “floral dress, looking simple but chic,” spies said, and the couple took over a corner table and kept a low profile. The 54-year-old star and her 25-year-old lover have been together for nearly three years. A spy saw them “kiss a few times” with Zaibat’s “arm around her.” The sweet scene was a far cry from the clip Madonna released earlier in the day of her “secret project” with Steven Klein that showed her in black underwear firing a gun at the head of a hunky male dancer.
