Fergie and groom-to-be Josh Duhamel wild pre-wedding bash.

Fergie aka Stacy Ferguson, 33, joined fiancé actor Josh, 36, who will officially tie the knot tomorrow had 75 friends and family over to the swinging-ring-a-ding Dakota Lounge in Santa Monica.

The couple were hailed with huzzahs from partygoers which included her former band mate Will.i.am from the Black Eyed Peas.
"Josh and Fergie usually spend so much time away from each other, so they wanted to make this week special and spend as much time together as possible," a source divulged.

The wild party which included dancing to the oldies (from the 80s) lasted until way past midnight.

After a champagne indulged evening Fergie, who sources say had a “blast”, will presumably return to her hard as nails pre-wedding workout regimen while Josh chills after finishing Transformers 2: The Rise of the Fallen.
