The singer’s second solo album, What’s Left Of Me, was released in May and has since been certified gold.

Lachey’s tour will focus on the East Coast, Midwest and South, with 26 stops planned in all. He’ll finish up at the Touhill Performing Arts Center in St. Louis, Mo., October 26.

Lachey last hit the road in 2001 as a member of 98 Degrees. The group reportedly plans to record a new album for release next year.

Although he’s been keeping busy with music lately, Lachey appeared in two feature films last year and has several TV projects in production. He and ex-wife Jessica Simpson finished up their “Newlyweds: Nick & Jessica” reality series in 2005.
