Kevin Federline, Britney Spears' ex-husband, has spoken out about the singer's conservatorship struggle and why he remained mute during it.

 In a new preview for his 60 Minutes Australia interview, the 44-year-old backup dancer was shown discussing Spears' conservatorship and their children.

The interview follows the recent quarrel between the former couple.

During the episode, which is set to air on September 4th. Federline stated that he couldn't let Spears' legal turmoil become his concern since he had to continue to prioritise their children, Sean Preston, 16, and Jayden, 15.

Kevin opened up about Britney's conservatorship battle in the teaser video, saying, "I felt terrible for her.

I truly was." "I still feel horrible," he added, according to US Weekly.

Federline went on to say, "The lads, the lads, the lads. I had to be concerned for them. I was unable to participate.

Kevin and Britney married between 2004 and 2006. Spears' conservatorship lasted 13 years and ended in November of last year.

Spears was subjected to the legal contract in 2008, following her widely publicised highs and lows following her divorce from Federline.

Britney recently married her longtime partner Sam Asghari, and while her sons were not present, Federline said, "Although the boys will not be in attendance, Kevin and the boys are pleased for Britney and wish her and Sam all the best going forward.
