Britney Spears' son was hit last night during a Las Vegas brawl between her bodyguard and a photographer.
The troubled pop star told police that one of her two sons - who has not been named - was assaulted during a scuffle between the snapper and her security.
Pop princess Brit had been at the Wynn Hotel and Casino for less then 24-hours with her children when the fight broke out.
Police did not immediately file charges against the photographer but Britney's bodyguard was cited for misdemeanor battery.
Police said the star's bodyguard, Julio Camera, hit the snapper who was trying get pics of the singer as she made her way though the hotel.
In response Britney filed a crime report on behalf of one of her sons saying a second photographer had battered her son and her bodyguard in an earlier clash.
The fight could not have come at a worse time for Spears who was already under fire for her parenting and for taking her kids away to Sin City amid concerns from her family about her recent erratic behavior.
The 'Toxic' hitmaker and her brother Bryan flew to Vegas in a private jet on Wednesday afternoon with her sons Sean Preston, 22 months, and Jayden James, 10 months.
It is not clear which of the boys was caught up and hit in the fight.
Las Vegas cops said that they were alerted to a disturbance at the Wynn Hotel and Casino just before midday.
A police spokesman said: "Responding officers determined that a private security officer, later identified as Julio Camera, was escorting Britney Spears through the Wynn property when an altercation occurred between Mr Camera and a photographer who was attempting to take pictures of Ms. Spears.
"It was alleged that during the altercation the photographer was battered by Mr. Camera. Detectives from the violent crimes section responded and, following their investigation, Mr Camera was issued a citation for misdemeanor battery.
"The photographer received minor abrasions during the incident.
"A second Crime Report was also filed by Ms Spears on behalf of her minor child. In that report it was alleged that prior to the above incident a second photographer, identified as Kyle Henderson, battered both Mr. Camera and Ms. Spears' child , who was at that time being held by the security officer."
Both incidents are still under investigation by police.
The trip could cause the star problems in her custody battle with ex-husband Kevin Federline.
Under California law, neither parent is allowed to take a child out of state without written permission from the other - or by obtaining a court order. According to a source close to Federline, Spears failed to notify her ex or his attorney, Mark Vincent Kaplan, that she was taking the children to Las Vegas.
A lawyer for Spears did not respond to calls for comment.
