Britney Spears protected her kids following her 13-year-old son Sean Preston’s alleged altercation with her father Jamie, according to her ex-husband Kevin Federline’s lawyer.

On Aug. 25, Federline and his attorney Mark Vincent Kaplan filed a police report at the Ventura County Sheriff’s station against the singer’s father Jamie Spears, alleging he physically abused Sean during a visit at his home one day prior.

According to Kaplan’s testimony as recorded in the police report, Spears’ 12-year-old son Jayden was also present during Jamie and Sean’s fight. The Blast reports that Jamie allegedly “violently shook” Sean after breaking down a bedroom door to reach him.

“Britney did the right thing and removed the children and took them out of there,” says Kaplan, who adds that Federline still wants his ex-wife to have “continuing and meaningful contact with their mother.”

Spears’ sons were also recently granted a restraining order against their grandfather, 67, that was filed by Federline and Kaplan.
