And so are the rivalries as the show's stars fight to fill spots on their teams of 16.
Christina landed sought-after pop singer Adriana Louise, who performed Jessie J's "Domino" and turned all four judges round.
On night one, De'Borah, who spoke about being pushed out of her church choir for her tomboy style and for being gay, impressed Christina and Cee Lo with her performance of "Hey Soul Sister" by Train. She ended up with Christina.
Bryan Keith, the 22-year-old son of Grammy-winning musician Ray de la Paz of the Spanish Harlem Orchestra, also had four judges recruiting him with his performance of "It Will Rain" by Bruno Mars on night one of the show. He ultimately picked Adam. The Maroon 5 frontman will also count on Joe Kirkland, who sang "Gives You Hell" by The All-American Rejects, to give his team a boost.
Blake has fared well, landing wrestler and country singer Casey Muessigmann (pronounced "music man!"), who performed "Sweet Home Alabama," and mariachi singer Julio Cesar Castillo, who sang "La Bamba" in the first all-Spanish performance ever on The Voice. The night before he landed yodeler Gracia Harrison, whom Adam called the best country singer the show has ever seen.
MacKenzie Bourg, 19, earned the mentorship of Cee Lo after he sang "Pumped Up Kicks," by Foster the People. The "Crazy" singer swiped returning contestant Daniel Rosa from Blake. Rosa, who sang Gotye's "Somebody That I Used to Know" auditioned last season but failed to turn any chairs around. Trevin Hunte, who performed "Listen" by Beyoncé on night one, will also be on Team Cee Lo.
The Voice enters its third night of blind auditions on Wednesday (8 p.m. ET) on NBC.
