Kevin Federline releases videos of Britney Spears appearing to argue with her sons after the singer opened up on their 'harsh' decision to see her less

• Kevin Federline has responded to Britney Spears' Instagram posts about their children.
• Federline posted and deleted Instagram videos that appear to show the singer arguing with her sons.

Britney Spears' ex-husband Kevin Federline shared — and promptly deleted — videos on social media of the singer appearing to argue with her two sons.

Last week, Federline spoke with the Daily Mail about the pop star's relationship with their two sons, Sean Preston, 16, and Jayden, 15, and said they "have decided they are not seeing her right now." Federline won full custody of their children in 2008 after the couple divorced in 2007.

Since the interview, Spears and her new husband, Sam Asghari, have hit back on Instagram, saying her relationship with her children should be a private matter.

In a now deleted post, Spears said she felt it was "hateful" that her sons didn't interact with her when they came to visit her while she was under conservatorship, adding that they would go straight to their rooms.

The "Toxic" singer said her children told her this summer they wanted to see her less and that she had not seen them since. She added that this was a "pretty harsh decision."

In response, Federline posted three videos on Instagram that he said were taken by their sons. The videos, which Insider viewed before they were deleted from the platform, 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 the original 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."

Federline previously said Sean Preston and Jayden were distancing themselves from the singer over partially nude photos she'd shared on social media.

On Wednesday, Spears said in a now deleted Instagram post that while she was under conservatorship, she avoided being "argumentative" with her sons because she feared being sent away again.

"Yeah, I know that teenagers are just hard to deal with at that age … but COME ON, there's being rude then there's being HATEFUL … they would visit me, walk in the door, go straight to their room and lock the door !!!" the singer wrote. "The MONITOR would tell me that he just likes to be in his room … I'm like why come visit me if they don't even visit me !!!"

The singer added: "But I never said that because I have to be kind. Remember... if I speak up as a woman or say something argumentative like I did with a dance move saying no to it, I got sent to that place for 4 months."

Spears said Federline initially told her he wouldn't let their children decide to stop seeing her.

The pop star added: "It breaks my heart because it seems to be that these days, cruelty does in fact win, although it's not about winning or losing !!!. But I can't process how I dedicated 20 years of my life to those kids … everything was about them !!! For them to knock the breath out of me."

Representatives for Spears and Federline did not immediately respond to Insider's requests for comment.
