Adam Levine on 'The Voice': 'I don't know how I would do without it'

Adam Levine and Blake Shelton are the only two coaches to have been on all 12 seasons of "The Voice."

Other coaches Christina Aguilera, CeeLo Green, Pharrell Williams, Alicia Keys, Usher, Shakira, Gwen Stefani and Miley Cyrus have all sit in the spinning red chairs for at least one season, but Levine and Shelton are lifers. And the Maroon 5 frontman told Carson Daly and Matt Lauer why he can't leave the show on the "Today" show Wednesday morning.

After Lauer called attention to his presence on every season of the singing competition -- "You were so young when all of this began!" -- Levine expressed his disbelief in the "crazy" fact.

"12 seasons in, like, 5 minutes it seems," he said with a laugh. "It's such a crazy thing. [The show] is a family, too. It is such a tight-knit thing at this point that I don't know how I would do without it, almost. It's bizarre -- it's a permanent figure, it seems, in [my] life."

Levine also took the opportunity to note that the series is showing a trend of having two female coaches each season after years of only featuring one. Stefani and Keys are coaches this season, and Keys and Cyrus were coaches together in the fall.

"It's really nice, actually," he explained. "There was always the lone female who had to kind of fend for herself with these three frat boys in this group. It was tough. I don't envy it."

"The Voice" airs on NBC Mondays at 8/7c. The Battle Rounds start next week.
