Josh Duhamel (left), Cesar Millan and Fergie
and husband Josh Duhamel
are ready for baby
– but can their dog say the same?
The singer, who will soon welcome her first child, a son
, with Duhamel, seems to be getting a helping hand, er, paw from Dog Whisperer
".@joshduhamel & I getting our doggie daughter ready for her new brother," Tweets the mom-to-be
, who also shared a snapshot of the trio joined by their dachshund, Zoe
And if Zoe is anywhere near as excited as dad, meeting her brother won't be a problem.
"We're as ready as we can be," Duhamel previously told PEOPLE
. "The whole idea that I get to be a dad is something I've always dreamt about."
