Jayden James had a bite mark and bruises on his body when cops came to take him out of Britney Spears house, but it’s not what you think.

Us reports that in the LAPD report of the incident, police observed a bite mark and multiple bruises on Jayden, but that Kevin Federline’s bodyguard told them that there were already there when Jayden got to Britney’s. In fact, it was his older brother Sean Preston who bit Jayden.

The report also notes that no force was used to get into the bathroom where Britney was holding Jayden.

In case you care where Britney is now, she showed up at her house in Los Angeles again yesterday with her latest boy toy.

Britney Spears cousin and assistant Alli Sims had to use a hammer to open the door to the bathroom where Britney and Jayden were locked in. After police got a hold of Jayden Britney said Jayden had a bruise on his arm, but "she said she did not do it." Jayden was taken to the hospital in an ambulance, then later released in Kevin Federline’s custody.

The picture above is when Britney almost dropped Sean Preston on his head, but she wouldn’t let go of the drink in her other hand to keep Sean from hitting the ground.

Last evening two ambulances left Britney Spears house, both headed for Cedars-Sinai Medical Center, one transporting Britney, the other had two-year-old Jayden James in it.

A car carrying Jayden’s older brother Sean arrived at K-Fed’s home a short time later. No word on what Jayden was being treated for.

I hope Britney didn’t hurt Jayden. Maybe he just couldn’t stop crying after Britney went crazy and created drama with police and helicopters circling the house. This is what happens when we leave Britney alone instead of getting her the help she needs so desperately.

Sean Preston was loaded into a car to go home with daddy Kevin Federline.

Kevin Federline, who is concerned about the mother of his children, arrived at the hospital to check on Britney’s condition.

Britney’s dad, Jamie Spears who didn’t spend Christmas with the family because he was upset, arrived at the hospital too. He looks like he’s a lot of help. Sam Lutfi, who needs to get a real job, also showed up.

Britney Spears was just wheeled out of her home on a gurney by paramedics. Britney is being taken to a local hospital on a "medical hold." This means Britney is being held for an involuntary mental health evaluation. Cops said Britney was “under the influence of an unknown substance.” Probably because she was acting crazy, so they would like to believe it was the drugs that made her act that way, however, they sent her for a mental health evaluation just to be on the safe side.

Mental health professionals can hold a person against their will for up to 72 hours while they evaluate them. A personal can be sent for an involuntary mental health evaluation if the person threatens to harm themselves, another person, or property.

Britney Spears is in big trouble. Mark Vincent Kaplan is going to have an emergency hearing to put more restrictions on Britney’s custody rights after all this went down. TMZ reports:

LAPD has been called to Britney Spears’ house in Beverly Hills for what we’re being told is a "family custody dispute."

LAPD tells us the call came in around 8:00 PM PT this evening, but they would not tell us who made the call or what the specific problem was. Officers, we’re told, are still on scene.

Spears, who was nearly two hours late for today’s scheduled deposition in her custody case, was reportedly scheduled to have her sons tonight until 7:00 PM.

Us is reporting K-Fed’s bodyguards went to pick up Sean and Jayden at Britney’s home this evening after her scheduled visitation, but Spears refused to turn the kids over. Police were then called. Britney’s soon-to-be ex- attorney Sorrell Trope told the mag, "In a normal case when someone shows up with a certified court order saying the kids need to be somewhere else, the police see to it that the order is obeyed. But that is in a normal case."

Another ambulance, more fire trucks and several additional police cars have just rolled up to Britney’s house. One person on the ground described the situation to us as "scary."

TMZ is at Britney’s house in Beverly Hills as several more police cars, fire trucks, an ambulance and a police chopper have now all descended on the popwreck’s humble abode. Don’t let ’em git me!!

We’ve learned Spears has refused to turn her two sons back over to their daddy tonight, as ordered by the court. LAPD tells us they’ve been called to the home to deal with the family custody dispute.

Sources confirm to TMZ that K-Fed’s attorney Mark Vincent Kaplan was at Britney’s home earlier, but has since left.

Britney needs to listen to her lawyers, but she won’t because she knows everything.

LAPD Officer Lee says that police are trying to resolve the family custodial issue. Mark Vincent Kaplan and Anne Kiley were present at Britney’s house and said Britney was “hysterical and just wants to keep the kids overnight.” Sources told Page Six, "someone is being transferred to the hospital for a mental evaluation." Mental health professionals can hold a person against their will for up to 72 hours while they evaluate them. A personal can be sent for an involuntary mental health evaluation if the person threatens to harm themselves, another person, or property.

The kids are safe, and back in Kevin Federline’s custody. Cops said Britney was “under the influence of an unknown substance.” The commissioner will not be happy.
