The singer is offering himself up for a dream dinner date to raise money for the VH1 Save the Music Foundation, which aims to keep instrumental music education programmes up and running in schools.
The highest bidder and a pal will be flown to Los Angeles, where Lachey will wine and dine them. The lucky pair will also be put up in a luxury hotel for a night and sent on a $500 (£330) shopping spree as part of the grand prize.
Bidding on the online auction kicked off on Monday and ends on 1 October.
