Just call them the O'Duhamels! Fergie and hubby Josh Duhamel got down at Confidential Night Club in Los Angeles on Saturday night. Fergie, who was wearing all green, danced and cheered on the crowd while bandmate apl.de.ap played her hits; meanwhile, Duhamel – who arrived in a beanie but later revealed his mohawk – pulled out his iPhone and recorded the scene.

The couple, joined by Fergie's sister Dana and Real Housewives of Beverly Hills stars Adrienne Maloof and Paul Nassif, were on hand to celebrate not only St. Patrick's Day but Voli trainer Don-A-Matrix and Fergie's new Voli light vodka drink, "The Ferguson." – Jessica Wedemeyer
