Britney Spears' ex Kevin Federline posts videos of her arguing with their children

Britney Spears' ex-husband Kevin Federline has posted videos of interactions between the singer and their sons after she accused him of exposing the teenagers to marijuana.

The first clip appears to show Spears standing in the doorway of a dark room where the two boys are filming, with the singer apparently reminding her son's it was '[her] house' and therefore she had the right to enter the room.

The second and third clip appears to have been filmed inside a car, where Spears is in the passenger seat while the two boys are sat in the back.

In a caption alongside the clips, Federline said he could not 'sit back' and let his sons be 'accused', adding: "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."

A back-and-forth between Federline and Spears began when Federline told ITV the children were distancing themselves from Spears after she posted near-naked photos online.

Spears slammed the comments as 'hurtful' and said the situation should have been dealt with 'privately'.

In response to Federline's videos, some social media users have argued Spears was not doing anything wrong and was instead simply parenting her children.

UNILAD has contacted representatives of Britney Spears for comment.
