Sources claim that Sean allegedly “felt unsafe” and locked himself in a room after an argument with Jamie, but he managed to break in and “shook” the boy.

"There was a disagreement that occurred while Britney and the children were visiting Jamie at his home that led to a physical altercation that was observed by [their other son] Jayden," Federline's representative reportedly said.

Jamie, the Grammy award winner's father was previously her conservator but stepped down after the alleged incident and requested her care manager, Jodi Montgomery, to fill in the role temporarily. Montgomery will take the position until January 31, 2020.

This April, Britney reportedly checked into a mental health facility.
