Britney Spears' father Jamie has been banned from seeing his grandson after he was allegedly involved in a ''physical altercation'' with her 13-year-old son Sean last month.
Britney Spears' sons have reportedly been granted a temporary restraining order against their grandfather.
The 'Toxic' hitmaker's father Jamie Spears is allegedly being investigated for abuse after the singer's ex-husband Kevin Federline filed a police report at the Ventura County Sheriff's station accusing him of being involved in a ''physical altercation'' with their 13-year-old son Sean.
A source told TMZ.com that Jamie allegedly ''broke down a door'' to get to his eldest grandson and grabbed him during the heated exchange but there were ''no visible bruises'' on him.
Although it's not thought Sean sustained any injuries during the incident, which reportedly happened on August 24, Kevin doesn't want Jamie any where near him or Jayden, 12.
Kevin's lawyer Mark Vincent Kaplan told PEOPLE.com: ''Britney did the right thing and removed the children and took them out of there [the house after the incident].''
Police have reportedly already interviewed witnesses and have passed the evidence to the district attorney, who will decide whether to charge Jamie over the alleged incident.
Meanwhile, the Britney, 37, is currently embroiled in a legal battle with her father - who has had control of the pop star's affairs for the past 11 years - as she's asked the court to free her of the conservatorship or to grant her more freedoms.
The 'Toxic' hitmaker appeared in front of a judge at the beginning of May to alleged that Jamie was responsible for having her committed to a mental facility and forced her to take drugs after she checked into an unnamed facility for 30 days in April.
She argued that under the rules of the conservatorship Jamie does not have the power to either commit her against her will or make her take prescription pills.
The judge presiding over the case has since ordered a thorough investigation of all the people who take part in Britney's conservatorship in order to properly assess whether the restraints on the singer should be loosened or modified.
The probate court investigator will conduct extensive interviews with all the people involved in a conservatorship case, including guardians, conservators, doctors and even law enforcement officials who have had contact with the subject.
The investigator will also be reviewing medical and financial records, including custody agreements surrounding her two sons and contractual obligations.
Following the court case, the singer's fans started the social media campaign under the ''#FreeBritney'' hashtag to call for the conservatorship to end.
