Fergie and Josh Duhamel expecting first child

Congrats are in order for Fergie and Josh Duhamel!

The married duo is expecting their first child together, the Black Eyed Peas songstress and actor both confirmed Monday.

“Josh & Me & BABY makes three!!! #mylovelybabybump,” Fergie, 37, tweeted yesterday, hashtagging a nod to the Peas’ song “My Humps,” which has a lyric “My lovely lady lumps.”

Meanwhile, Duhamel wrote: “Fergie and Me and BABY makes three.”

Duhamel, 40, sure knows how to keep a secret — he’s been on the talk-show circuit for the last two weeks promoting his flick “Safe Haven,” co-starring Julianne Hough, and didn’t spill the news that he and his wife are expecting.

The pair married in 2009.

Fergie did not reveal how far along she is.
