Fergie pregnant Josh Duhamel LAX

On the same day they finally confirmed that they were expecting their first child, Fergie and hubby Josh Duhamel jetted out of Los Angeles International Airport.

Josh wore a baseball hat and jeans, but Fergie Ferg slipped into a pair of sexy leather pants and caught our attention in a bright yellow top and patterned scarf.
