Britney Spears' First Ex-Husband Arrested For Allegedly Trying To Crash Her Third Wedding

Britney Spears’ ex — to whom she was married to for just 55 hours in 2004 before the marriage was annulled — was arrested Thursday while allegedly trying to crash her wedding to longtime boyfriend Sam Asghari.

Jason Alexander is now facing charges of trespassing, battery and vandalism after he allegedly broke into the pop star’s Thousand Oaks, California home Thursday while livestreaming on Instagram, according to Page Six.

Ventura County Sheriff Office Capt. Cameron Henderson confirmed to Oxygen.com that deputies were called to the residence just after 2:00 p.m. after getting a call that there was a trespasser on the property.

“When we got there, we learned that the subject, Jason Alexander, was on the property without permission and there was an altercation between him and the security team that was on scene there,” Henderson said.

Henderson said the alleged battery and vandalism occurred while the private security team was trying to detain Alexander, although he declined to provide specific details about what that entailed.

Alexander was booked on an unrelated outstanding warrant from Napa County while deputies investigated the wedding incident.

The incident began — as Alexander allegedly livestreamed himself — when he walked up a trail to the singer’s property.

“I’ve been coming for 3 weeks up here, I’ve been scoping this s--- out,” he said to a man sitting in a camping chair, according to NBC News.

As he continued to make his way to the property, Alexander encountered another man on a golf cart, who asked him to leave or he’d call 911.

“Where’s Britney at?” Alexander responded before the video freezes.  

When the video picks back up, Alexander is inside the singer’s home. He continued to ask where Britney was as a man with a gun — who appears to be a security officer — attempts to confront him.

Alexander moved back outside and introduces himself to someone else as Spears “first husband.”

“I’m here to crash the wedding, brother,” he said.

The video footage also shows Alexander walking into a lavishly decorated backyard tent with an archway of roses and talking with the people setting up for the event, Buzz Feed reports.

At the end of the footage, Alexander is confronted by security and a scuffle breaks out.

After the incident, an emergency protective order was issued instructing Alexander to stay away from the star.

The unwelcome wedding crasher apparently did not derail Spears' wedding plans and Asghari’s manager Brandon Cohen later confirmed to NBC News that the pair had tied the knot.

“I am very ecstatic this day has come, and they are married,” Cohen said. “I know he wanted this for so long. He is so caring and supportive every step of the way.”  

Spears’ attorney Mathew Rosengart said in a statement to Oxygen.com that he is hoping Alexander is "aggressively prosecuted and convicted" and thanked the sheriff's office for their "prompt and good work." 

"This was an outrageous breach, which I am livid about, but fortunately Britney is completely safe and was a beautiful bride," he said.

Alexander had been a vocal public supporter of his one-time wife throughout the #FreeBritney movement to end the star’s now defunct conservatorship.

He was often seen at public rallies, but a source told Page Six her family became “disturbed” after the 40-year-old started showing up at their homes.

“They think it’s incredibly inappropriate and downright weird,” the source said.

Henderson told Oxygen.com that he was not aware of any prior incidents involving Alexander at Spears' Thousand Oaks property.

Alexander was booked into Ventura County jail, where he’s being held on a total of $22,500 bond, according to jail records.

Along with the trespassing, battery and vandalism charges, he’s also being held on an outstanding warrant out of Napa County for grand theft embezzlement and receiving stolen property.
