Has Kristen Wiig snared hot Strokes drummer Fabrizio Moretti? After unveiling a sexier look in the new issue of GQ — pouting in black underwear and high heels, with a Champagne flute — “Bridesmaids” and “SNL” star Wiig was spotted canoodling with Moretti, Drew Barrymore’s ex, at a Black Keys album party Monday night. Spies saw Wiig and Moretti “all over each other” at the rock ’n’ roll shindig at newly opened W Union Square club Lilium. “They were literally on top of each other,” said a source who witnessed the comedienne and the snare-beater keeping time together. GQ recently dubbed Wiig its honorary “Bro of the Year” and Jon Hamm wrote, “Kristen is incredibly shy . . . But this is a woman who wore coconuts on her [bleeps] on ‘SNL’; she can go to the craziest, most grotesque places on the planet in character.” The fete was to celebrate the Keys’ new album, “El Camino,” following a show at Webster Hall. The band is back on March 12 to play the Garden with Arctic Monkeys.
