Soon-to-be newlywed Fergie and fiance Josh Duhamel celebrated their final days as part of the single set with joint bachelor and bachelorette parties in Hollywood last night.

“They wanted a more tame party and wanted to do it together,” a spy revealed to In Touch Weekly on Wednesday.

But that doesn’t mean fun wasn’t in the air.

The Black Eyed Peas songstress, 33, reportedly received “plenty of naughty gifts from all her girlfriends,” the insider adds.

Fergie and Josh, of Transformers fame, have been dating for more than four years and will wed this Saturday, January 10, in Southern California.
