Nick Lachey will definitely have his hands full on the 98 Degrees tour this summer! The new dad and his bandmates Drew Lachey, Justin Jeffre, Jeff Timmons are planning on bringing their families with them for the ride, and Nick tells Us Weekly his nearly 8-month-old son, Camden, with wife Vanessa Lachey has already been keeping him busy.

"The baby's growing up quick, starting to crawl and getting into all kinds of trouble and it's fun," Nick tells Us Weekly's Ian Drew in an exclusive interview. "It's fun being a dad. It's fun having a son and family life is great."

But after a 13-year hiatus, the 39-year-old singer is looking forward to kicking off 98 Degrees' joint summer tour with Boyz II Men and New Kids on the Block at the end of May.

"[I'm] excited to be back with these jokers, doing what we like to do," he shares, "which is performing and singing together, and getting out there on tour this summer."

But Lachey won't be the only one trying to juggle the tour with family in tow. Nick's brother Drew, 36, has two children, and band member Timmons, 40, is a father of four.

"We're gonna shove all the wives and kids in one bus and then we'll have our own bus like the old days," Timmons jokes. "No, I mean, we were fortunate enough to have this experience the first time around with the four of us and we had good crew people."

"It was a great experience, but you want to share that with other people," he explains. "We're fortunate enough, blessed enough, this time around to bring our families, our wives, our kids and our friends along with us."

98 Degrees' new album, 2.0, is available now. Watch the band's exclusive interview with Us Weekly in the video above.
