"Josh & Me & BABY makes three!!! #mylovelybabybump," Fergie tweeted Monday, along with a photo of herself and Duhamel as children.
Her 40-year-old Safe Haven star hubby also announced the news on his Facebook page, writing "Fergie and Me and BABY makes three. #MyLovelyBabyBump," along with the same photo.
While Duhamel stayed mum when we asked him about baby bump rumors at his recent Safe Haven premiere in Los Angeles, the thesp did say having a child would be his "greatest life achievement."
The 37-year-old Black Eyed Peas singer and Duhamel tied the knot in 2009 in a lavish, star-studded ceremony in Malibu.
