Everyone in the Duhamel household is getting ready for the new arrival - and that includes dog Zoe.
"@joshduhamel & I getting our doggie daughter ready for her new brother with @cesarmillan," mom-to-be Fergie tweeted Tuesday, along with a photo of her, husband Josh Duhamel, their dachshund Zoe and famous dog trainer Cesar Milan.
The Black Eyed Peas singer, 38, is expecting her first child with Duhamel any day now.
Her "Safe Haven" hubby, 40, who's seen holding Zoe in the photo while barefoot in sweatpants, later tweeted, "Curious how your pets reacted when you brought home your first newborn child. Any advice?"
Last June, Duhamel expressed confidence to Us Weekly that their dog would be able to handle a baby in the family.
"We know how Zoe is and she's really good around kids," he said.
Even so, the couple seemed happy to get an assist from Milan, the star of the hit series, "Dog Whisperer with Cesar Millan."
He later posted some tips on his website, including establish yourself as the "pack leader," use an item, like a burp cloth, to introduce the baby's scent to the dog and establish boundaries around the nursery.
