Most brides and grooms-to-be have one last night of debauchery away from each other before they tie the knot, but Fergie and Joshua Duhamel can't stand to be separated for even an evening ahead of their nuptials this Saturday.

They held their joint stag and hen nights at Dakota Lounge in Santa Monica, California, with Fergie flaunting her improved figure in a shimmery black dress - she's said to be desperate to shed excess pounds before her big day after gaining weight for her role in movie musical Nine.

This couple seem to be determined to do everything differently - she's refusing to wear white too, opting for a "bold and bright" Dolce and Gabbana number instead.
