Fergie and Josh Duhamel are preparing to be first-time parents. The Black Eyed Peas singer is pregnant.

Fergie, 37, announced the happy news on Twitter today, posting: "Josh & Me & BABY makes three!"

To celebrate the announcement, the mom-to-be also shared photos of herself and her hubby as children.

She attended the Los Angeles premiere of "Safe Haven" on Feb. 5 (pictured above), and cleverly hid her condition in a black shift dress.

Earlier this month she sparked pregnancy rumors after being photographed in loose-fitting clothing and coats. However, in September, Fergie denied rumors she was pregnant when fluctuating weight had her wearing looser clothing.

Fergie and Duhamel wed in 2009.
