“Bridesmaids” and “SNL” star Kristen Wiig’s romance with Strokes heartthrob and drummer Fabrizio Moretti hasn’t missed a beat. The pair we can’t resist calling Wiigetti were spotted “partying pretty hard” at dimly lit subterranean lounge Cabin Down Below on Sunday night, even though Wiig and her “Saturday Night Live” pals had partied late the night before after their NBC show was hosted by Charles Barkley. Also hanging with the hot new couple (who oddly requested songs from the “La Bamba” soundtrack), along with a few other friends, was Sean Penn, who is directing Wiig and Robert De Niro in “The Comedian.”
