Fergie sunglasses mom spandex workout plaid hat black eyed peas

One of our New Year's resolutions is to have the same dedication to working out that Fergie has ... the hot mama never takes a day off from her cardio!

On Monday afternoon Fergie Ferg slipped into some spandex and went for a hike in the Hollywood Hills, and though the holidays have been mellow for the new mom, she will be working tonight, as she's set to host the West Coast party on Dick Clark's New Year's Rockin' Eve with Ryan Seacrest.

Still, the singer says it's "all about baby Axl this year," telling People her four-month old is even getting into the holiday spirit. Well, kinda. "It's really cute because he's been looking at the tree and the lights in our house and he's very fascinated by this and the ornaments," she says. "He wants to touch it and feel the way that the bristles feel on his feet and hands and he's very curious about it. It's such a happy feeling as a parent to see the curiosity in your child's eyes." Awww!
