A representative for the Black Eyed Peas singer confirmed the news Monday. Fergie's actor husband Josh Duhamel tweeted about the news with joy, saying: "Fergie and Me and BABY makes three."
The 37-year-old Fergie and 40-year-old Duhamel married in 2009. She joined the Black Eyed Peas when the group released its third album, "Elephunk," in 2003. The foursome is known for its pop-inspired hip-hop tunes like "My Humps," ''I Gotta Feeling" and "Boom Boom Pow."
Fergie launched her solo debut, "The Duchess," to much success in 2006. It featured five Top 5 hits, including "Fergalicious" and "Big Girls Don't Cry."
Duhamel has appeared in the "Transformer" films and most recently in "Safe Haven."
