Josh Duhamel, Fergie dog walking

The family that works out together, stays together.

Fergie and hubby Josh Duhamel spent some quality time with one another on Saturday in Los Angeles. Thanks to these joint exercise sessions, as well as hikes and runs, the Black Eyed Peas frontwoman has lost all her baby weight. She's as fit and trim as ever after giving birth to a baby boy in August.

The singer showed of her slim waist and toned legs in an athletic jacket and leggings. And in true Fergie fashion, she accessorized the look with giant headphones, a bizarre cap and bedazzled fanny pack.

Although their son Axl Jack is still too young to hit the pavement with them, the other love of their lives, their dachshund Zoe, joined them outside. Before their baby's birth, the couple enlisted Dog Whisperer Cesar Millan to get their "doggie daughter ready for her new brother" (as Fergie tweeted). Their precious pup is such a significant member of their family that she even made an appearance on their Thanksgiving card.
