Access Hollywood reports that the 33-year-old singer—born Stacy Ann Ferguson—and her 36-year-old Transformers actor fiancé will tie the knot over the weekend of January 9 to 11 in Southern California.

The nuptials have been a long time coming; Ferguson and Duhamel met in September 2004, and became engaged last Christmas. 

And now Fergie has two reasons to celebrate—aside from her upcoming wedding, the singer's turn as a porky hooker in the upcoming musical Nine will no doubt propel her into big-screen stardom.

Speaking of big, Fergie had better hurry—she doesn't have much time to shed those extra pounds she packed on for the flick so she can fit into her wedding dress.

It might be a good idea for her to practice walking down the aisle while she's at it.
