The last time Blue Bloods' star Donnie Wahlberg dropped by, he and the rest of the New Kids on the Block helped pull off an amazing surprise for one super fan! Donnie says that he still loves the fan reaction after all these years, but that it's changed somewhat since the 80s. "It’s one of the good things about doing music again after all these years, " he tells Rachael. "The little girls who used to like grab and rip our clothes off and pull our hair, they’ve grown up into women and they’re nice now!"

Donnie shares that his 9-year-old son Elijah has caught the music bug as well. "He came out on tour during one of the summer tours," Donnie says, "and he said, 'Dad, I want to come out and sing on Step by Step. I want to sing step 5.' And I was like, 'Why step 5?' and he said, 'Well, because Jon is my favorite New Kid!' So he started singing step 5 and Jordan would be playing the keyboards in the dressing room and I’d say, 'You’ve got to practice; Jordan is going to play and you practice.' He said, 'No, I don’t practice, dad, I just go out and do it.' And it’s great, it's really sweet."
