Jason Alexander, Britney Spears’ first husband who livestreamed himself crashing her wedding on Thursday afternoon at her California mansion, is in the custody of the Ventura Sheriff’s Department having been charged with trespassing, vandalism and two batteries after a couple of altercations with Britney’s security guards.

Alexander was captured running through hillsides as he neared the back of Spears’ house, minutes before his arrest. 

He was able to climb a fence and descend a steep hillside, then slip into the venue. All the while telling security who he was and why, just hours before the fairytale wedding ceremony began. 

Alexander was the third person to be arrested in just 13 months. Sources from police revealed that he was also wanted for felonious larceny.

Last time he was in custody, he was arrested for driving while under the influence and violating security protocol at an airport. Alexander was previously arrested for stalking and violating an order to protect a woman unidentified in December 2021. 

On Thursday night, Spears’ attorney revealed he was ‘absolutely livid’ after Alexander crashed the pop star’s wedding venue and demanded he be locked up. 

Mathew Rosengart, a former federal prosecutor with a reputation that has seen him represent a host of high-profile clients since he went into private practice in 2001, said he is ‘personally working with the sheriff’s department to ensure Mr. Alexander is aggressively prosecuted to the fullest extent of the law.’ 

“Jason Alexander was handcuffed and taken into custody. I express my thanks to the Ventura County Sheriff’s Department for their prompt response and good work,’ Rosengart, told TMZ in a statement. 

Rosengart’s swear to Alexander prosecution capped an afternoon filled with drama at Spears’ Thousand Oaks mansion in California hours before her wedding to longtime boyfriend Sam Asghari.

Alexander was captured on camera by a photographer. 

Alexander stated that Britney had invited him to the event. Before he claimed proudly that he was there for the ‘crash of the wedding’, he said that Britney was his “first and only” wife.

He managed to get inside the tent decorated with pink roses before being confronted again by security forces.

Alexander was quickly tackled and taken to the ground. The Ventura County Sheriff had been called. Alexander’s actions revealed an astonishing breach of security around him, as shown in overhead photos.

Rosengart said to TMZ that Alexander crashed and tried to run away from him, and that he wants Alexander arrested. 

Alexander and Spears were married in Las Vegas, Nevada in 2004, and they were together for 55 hours.

They would allow Britney and me to continue our relationship and, if Britney felt the same in six months, they would grant us a marriage. “So, I didn’t have any reason to doubt it. That was what I believed to be the truth.

Britney was able to communicate with me by phone. So we were talking every day and I still believed the story I was told, that they were going to let us continue to talk and then we would have this marriage … in the future if we felt the same way.’
