The latest season of The Voice is tugging on the coach’s heartstrings as two of them break down while on set.

The Blind Auditions continue after the start of season 9 and both Guy Sebastian and Delta Goodrem find themselves in the coach’s chairs.

Guy Sebastian was particularly emotional as his younger brother Chris took to the stage for another chance at the title.

Chris was on the first season of The Voice in 2012 and Guy said he felt the pressure of his younger brother competing.

"I'm so close to my brothers, I would die for them," Guy, 38, tells TV WEEK.

"We're such a tight family unit. That's why I was so nervous about Chris doing the show. He was approached last year, and after I had a year of being a coach, I knew it was a safe space for him to go back into."

Guy was very emotional after his brother sang.

"I was embarrassed by how I was after he sang," Guy says.

"You get emotional, but then I was crying a bit too much and went into the ugly cry. Then it got weird for everyone, and it was like, 'OK, we get it – he's your brother.'"

Delta also got emotional as All Star artist Jesse Teinaki returned to the show.

"I felt such a connection to him," Delta, 35, says of Jesse, who was on her team in 2019, but wasn't taken through to the live rounds.

"Jess is such beautiful person. I think he was one of the best auditions this year and it was very emotional. He's really special – for me, he's one of the highlights of the Blinds."
