TLC will air "Nick & Vanessa's Dream Wedding" (working title), a special to air just weeks after the couple's wedding date, which they are keeping top secret.
Lachey, 37, and Vanessa Minnillo, 30, have been dating since 2006 and got engaged last fall. He and ex-wife Jessica Simpson documented their own wedding and early married life on MTV's Newlyweds.
"We're lucky to have such passionate and loving fans, and we thought partnering with TLC on this special would be the best way to share the exciting journey we're on with all the people that support us and our relationship," Lachey and Minnillo said in a statement.
The special will feature footage from their joint wedding shower, Minnillo's wedding dress search and the ceremony itself.
