Backstreet Boys Are Taking Their Families On DNA Tour: 'It's Like National Lampoon's Vacation'

Backstreet's back — with kids! Backstreet Boys are on the road again after a two-year hiatus for their DNA World Tour, and this time around they're bringing their families along for the ride. The boys share how their kids give them a fresh perspective on tour life, and praise their "amazing wives" for being their rocks. Nick Carter also dishes on his stay-at-home dad life with his baby girls, and Brian Littrell praises his 20-year-old son for making a career in country music.
