Fergie & Josh Duhamel: We Sing Songs to Baby Axl!

Fergie tunes out the world with headphones as she goes on a jog with her personal trainer on Saturday (November 23) in Brentwood, Calif.

That same day, the 38-year-old entertainer’s hubby Josh Duhamel attended a 2K run-walk as part of the PUMA Run Walk For Philippine Relief in Santa Monica.

“We sing (songs) and we put them on video,” Fergie recently told USA Today. “We’re like that couple in Best in Show that sings about their dog. The cornier the better. We love it and we think our son loves it.”

She added, “Josh has a good voice! He has his rock voice and he has character voices, because he does a lot of voiceovers. And, so do I, so we’re just really confusing our son!”
