Fergie Hiking canyon hills

Hot mama!

Fergie went for a hike in the Hollywood Hills yesterday, and the singer showed no sign of lingering pregnancy pounds as she squeezed in a mid-morning exercise session.

The Black Eyed Peas front woman looked unbelievable in a black spandex outfit with a flannel tied around her waist, and we're dying to know what she was jamming to with those headphones!

This will be Fergie Ferg and husband Josh Duhamel's first Christmas with newborn son Axl, so we wonder how they will be celebrating?

We caught the TV actor grabbing coffee this morning before dropping off an older woman at LAX, so maybe grandma already came to town for a visit!
