Nick Lachey put in some unexpected work during an appearance on a US chat show yesterday (03AUG05), when he was made to perform a range of exercises with his co-host sitting on him.

The former 98 DEGREES star filled in for LIVE WITH REGIS AND KELLY host Regis Philbin, and interviewed Seann William Scott, who co-stars with his wife Jessica Simpson in the new movie The Dukes of Hazzard.

But during a later segment with fitness expert Jillian Michaels, Lachey was stunned when he was ordered to perform pushups and lunges with co-host Kelly Ripa on his back.

The pop star hesitantly obliged, while jokingly grumbling, "What is (Ripa) working out right now?"

Lachey and Ripa also competed in a mini Soap Box Derby race at the end of the show.
