Guy Sebastian opened up on Wednesday about a break up with his wife Jules.

The Voice Australia coach, 41, revealed on Sunrise he and Jules were dating in 2000 but she briefly dumped him before his appearance on Australian Idol.

‘I didn’t think we would get back together,’ the singer told co-hosts Natalie Barr and Matt Shirvington.

‘I was 18 when we first got together and I think I was 21 (when we broke up) and she kind of broke my heart.’

‘She broke up with me and then Idol happened and I moved to Sydney and I didn’t think we’d get back together, I wasn’t sure.’

Guy explained he eventually realised that he and Jules had ‘so much history and she always loved him’.

Guy married Jules in late 2007 after eight years of dating, and they share two sons, Hudson, 11, and Archie, nine.

Last month, the singer revealed his wife was hesitant to have children when they first started dating.

He spoke to Who Australia about Jules’ fear of motherhood.

‘Jules was a tomboy growing up. You know how some women growing up are kind of like, “I just can’t wait to be a mum?”,’ began the Australian Idol star.

‘Whereas Jules was petrified of it. I never heard the words “I want to be mum” ever come out of her mouth because I think she was scared that she wouldn’t do a good job,’ he said.

Despite her reservations, Guy claims Jules has naturally taken to motherhood with the couple’s two sons.

‘The thing that I’ve seen her do unbelievably well is be a mum,’ the pop star said, praising his wife.

‘I think you have a newfound love for your partner when you see them in a role like that – nurturing and looking after the people that matter the most to you. She’s killing it!’ he added.
