Fergie Rocks Out with Motley Crue for Sunday Afternoon Hike

Fergie goes for a hike with her personal trainer on Sunday afternoon (November 17) in Brentwood, Calif.

The 38-year-old singer was sporting a Motley Crue band tee-shirt, a sweatshirt, leggings, and sneakers for her workout session that day.

“Please help @apldeap’s beloved Philippines affected by Super Typhoon #Haiyan. Every little bit counts! #UNICEF,” Fergie tweeted over the weekend along with a link to UNICEF‘s website.

Over the weekend, Fergie‘s husband Josh Duhamel was down south in Texas attending an event for the Formula 1 event.

FYI: Fergie is carrying a Rails Hunter plaid shirt around her waist.
