As Fergie celebrated Halloween at NYC club Avenue, the Black Eyed Peas singer appeared carefree. Sipping white wine and vodka with pals Marc Jacobs and Kylie Minogue, "she was dressed up as Cleopatra and seemed to be in a good mood," a friend of hers tells Life & Style.

"We all had a blast." But all around her people have been buzzing about an explosive new report that Fergie's husband, Josh Duhamel, cheated on the star with an Atlanta stripper. Shortly thereafter, on Nov. 2, Fergie, 34, took a plane to Georgia. "She said she was flying out to see Josh," says an insider.

Josh, 36, who's been in Georgia filming Life As We Know It, reportedly met Nicole Forrester in early October at Tattletales Lounge, where she dances under the name "Delilah." He allegedly invited her back to his room at the St. Regis hotel, where they drank vodka, went for a drive, watched porn and had sex into the wee hours of the morning.
