Looks like Fergie wasn't lying when she sang about workin' out to keep her body staying vicious.

The duchess and her "Las Vegas" hunk Josh Duhamel got their fitness on yesterday in Santa Monica. The healthy couple did stretches, went for a jog and ran stairs. After the intense workout, the sweaty lovebirds congratulated each other with a hug and then hopped into Josh's truck and sped off.

T to the A, to the S T E Y.
