Michael Bublé is serious about defending his title on The Voice. Last season’s winning coach turned up the dial on the Feb. 10 episode of the competition series in an effort to attract hopefuls to his team.

The first time Bublé put his winning skills to good use wasn’t even for his own benefit. Bublé didn’t turn around when Hayden Grove performed “Mack the Knife,” but he had a special reason for feeling connected to the 31-year-old singer.

Watch his performance below.

“I started posting TikToks in 2020. Michael Bublé started posting some duets where he would allow another singer to sing with him. I did a couple of those,” Grove said in his intro video. “All the sudden, I saw [a notification that said,] ‘Michael Bublé is following you,’ and I lost my mind.”

Eventually, Grove attended one of Bublé’s concerts and the superstar promoted his TikTok during the show, leading to a huge gain in followers.

“I will forever be grateful for that moment,” Grove said, before he took the stage.

Adam Levine turned for Grove, but Bublé did not.

“This dude knows that I love him,” Bublé said after realizing who was behind the voice. “He knows that I follow him on TikTok.”

The reason he didn’t turn his chair had to do with Grove’s use of vibrato, a position he demonstrated himself by joining the contestant on the stage. First Bublé sang part of the tune himself, before coaching Grove through the exercise.

“I know he’s on your team and he’s going to dominate,” Bublé told Levine, “but I’m going to help you to help him because he has everything it takes.”

Michael Bublé Uses His Coach Replay Button

The next example was solely for Bublé’s own benefit. After Ricardo Moreno failed to get anyone to turn around during his performance of “Put Your Head on My Shoulder,” all the coaches blamed Bublé’s failure to push his button as the reason they didn’t push their own.

When it was his turn to speak, Bublé tried to explain why he didn’t turn around.

“Man, it’s hard for me because I’m so picky. I heard so much that I liked. The truth is,” he said before pausing and pushing his Coach Replay Button, immediately putting Moreno on his team.

“The Coach Replay Button, I love that thing. It isn’t just a second chance for the contestants, it’s a second chance for us coaches in case maybe we missed out,” Bublé told the cameras. “We don’t have to use it, but I think Ricardo has really distinct and different voice. I think it is powerful. I think he has the ability to go between genres. I’m really glad the Coach Replay Button was there, so I could still bring him home to Team Bublé.”
