Traditionally a bachelor party is considered the last chance for the soon to be married partners to have a final outing with friends. But the two are so in love that they have decided to throw a joint bash.
A source told In Touch magazine that the couple would have "a joint bash at a lounge in Santa Monica. They wanted a more tame party and wanted to do it together."
The 'Fergilicious' singer whose real name is Stacey Ferguson got engaged to actor Duhamel in December 2007 and has been eagerly awaiting their forthcoming wedding which will be held on Saturday in a undisclosed location in Southern California.
The source added, "She's getting plenty of naughty gifts from all her girlfriends. Everybody can't wait to help them celebrate."
All members of the hip-hop group Black Eyed Peas of which Fergie is a part would reportedly be attending the wedding.
