Bublé, Snoop, Gwen Stefani and Reba McEntire are serving as coaches on season 26 of ‘The Voice’.

Michael Bublé is Snoop Dogg’s biggest fan.

In a roundtable conversation with the season 26 coaches on The Voice, premiering exclusively with PEOPLE, Snoop asks Gwen Stefani, Bublé and Reba McEntire about their dream collaborators.

“When you finally met the artist that you wanted to work with your whole life, and you finally got to work with them, what was that feeling?” Snoop, 52, asks.

“I can’t tell you because you won’t believe me,” Bublé, 49, says. Snoop responds, “I will believe you.”

“I love you so much I’m not joking. My family loves you. I was so terrified that you wouldn’t be who you are. I was so excited to do this with you and people say, ‘No man. He’s got a great reputation,” he says, seemingly growing emotional.

The first day they showed up to film, the “Haven’t Met You Yet” singer was “so nervous” to meet the rapper — and he turned out to be “awesome.”

“It was huge for me because the truth is I was really excited,” he adds. “I was so excited to meet you and you’re better than I ever thought you could be.”

Stefani, 54, adds, “I felt the same when I got to hang with you at the MTV Awards on that couch.”

Snoop — who was flattered by Bublé’s confession — says that his dream collaborator was James Brown. When he met him, Snoop was filming the 2001’s Bones and he heard the late singer was trying to get in contact with him.

“I said, ‘Stop playing with me man. James Brown don’t want to meet me.’ And he drove all the way to my house and we spent about three hours at a picnic table just side by side,” he recalls. “We had microphones in front of him and in front of me and we just talked. He was telling me things about my life and career that are actually happening right now.”

After Snoop shares his story, he turns to look at McEntire, 69, and asked who she dreamed of working with.

“I never wanted to meet my heroes because I didn’t want them to disappoint me. Ever. I was doing shows with Merle Haggard and I did not want to meet him,” she says. “I did not want to meet him because I did not want to be disappointed because I looked up to him for so long and when I did he was the nicest, most cordial gentlemen and I was like, phew.”Michael Bublé

Adding, “But people like Loretta Lynn, Dolly Parton, Tammy Wynette, Barbara Mandrell, who I looked up to forever, all of them, sweet as they can be.”

Elsewhere in their conversation, the coaches discuss working in a recording studio for the first time and what it was like hearing themselves on the radio.

The season 26 coaching panel was announced in May following John Legend, Chance the Rapper and Dan+ Shay’s exits. Stefani is returning after briefly taking a break following season 24. Meanwhile, newcomers Snoop and Bublé previously served as advisors.

The Voice returns to NBC on Monday, Sept. 23 at at 8 p.m. ET.
