Kevin Federline said that he thought Britney Spears' father had good intentions by putting her in a years-long conservatorship.
The conservatorship ended last year after a long court battle in which Spears said in her testimony that she was put on medication against her will and her overseers wouldn't allow her to have her IUD removed to have children.
Spears also shared anecdotes about her father, Jamie Spears, "loving" having control over someone as powerful as her.
Federline, who was married to Spears from 2004 to 2007, and has full custody of their two sons, Jayden James and Sean Preston, said during a new interview with "60 Minutes Australia" that he believed Jamie Spears "saved" the "Circus" singer.
"A hundred percent, I feel like he saved her back then," Federline said when asked whether Jamie saved his daughter by putting her in the conservatorship.
Federline added that he "couldn't get involved" with the conservatorship because he had to look after their two sons.
"I wasn't involved in any of it so I really don't know how the conservatorship came about, I don't know whose decision it was," he said. "All I know is that you have a family that is worried about their daughter and trying to do whatever they can to help her. That's all that I knew."
Britney is currently in a feud with Federline after he spoke to the press about the "Toxic" singer's relationship with her sons.
Last month, Spears said in a now-deleted Instagram post that she felt it was "hateful" that her sons refused to interact with her when they visited her while she was under conservatorship. The pop singer added that it was a "pretty harsh decision" for the pair to say they want to see her less.
Federline responded by sharing videos, which Insider viewed before they were deleted from the platform, that appeared to show Spears arguing with her sons.
"I can not sit back and let my sons be accused in this way after what they've been through," Federline captioned his post. "As much as it hurts us, we decided as a family to post these videos the boys took when they were 11 & 12. This isn't even the worst of it. The lies have to stop. I hope our kids grow up to be better than this. #NeverFearTruth."
In light of criticism from Spears' lawyer for posting the videos, Federline defended the decision.
"I've spent the better part of my adult life turning the other cheek in response to attacks on me," he said during the "60 Minutes Australia" interview. "When our children are attacked I found the need to set the record straight to be overwhelming."
