Blake Shelton believes it will be a massive upset if Adam Levine loses The Voice's seventh season.

"If he doesn't win The Voice this year with three people -- three people! -- it is the most epic fail," Shelton told Extra following Monday night's performance show, which featured three of Levine's artists performing in the Top 5.

"I think someone should tell him that it's technically not over yet," Levine said in reply.

However, Levine's chances of winning are even better now. As of Wednesday morning, Levine has all three of his artists -- Damien, Matt McAndrew and Chris Jamison -- in the Top 4. Matt and Chris were voted into the Top 3 by home viewers, while Damien was selected by America as this season's "Wild Card" finalist.

Levine is apparently feeling pressure from more than just his fellow coach Shelton, who has his team member Craig Wayne Boyd in the finals as well. The Maroon 5 frontman's wife, Victoria's Secret model Behati Prinsloo, told Extra with complete confidence that Levine is going to win the reality singing competition this season.

"If she said it, it's true. Duh," Levine joked.

The Voice's final performance show airs next Monday night at 8PM ET/PT, followed by the finale on Tuesday, December 16 on NBC.
