But in a behind-the-scenes clip shared exclusively with PEOPLE, the singers show off their silly sides with their famous coaches. While in rehearsal, Laith Al-Saadi shows he’s picked up more than just musical tips from his coach, Adam Levine. “Hopefully it’ll shut Blake up,” the singer tells Levine about his upcoming performance. Quips the Maroon 5 frontman: “I’ve been trying for a long time to shut him up.” Elsewhere, coach Christina Aguilera shows off her dance moves and plays with contestant Alisan Porter‘s adorable kids, Pharrell mimics his team and Blake Shelton goofs around with his singers. “You’re blowin’ people away. You’re gonna do it again,” Shelton tells Paxton Ingram – who picked a Whitney Houston song – in rehearsal. “You’re gonna do Whitney Houston? I mean, anybody can do Whitney Houston. I do Whitney Houston all the time in my shows.” The Voice airs Mondays and Tuesdays at 8 p.m. on NBC.
