Britney Spears' wedding dramatically interrupted by ex Jason Alexander

Jason Alexander was Britney Spears' first husband who live-streamed himself crashing her wedding at her California mansion.

In a 10-minute-long Instagram live video, Alexander can be seen scaling a fence on the perimeter of Spears' property as he documents exactly what he is about to do.

He encounters a number of security personnel and openly states his name and intention: 'I'm Jason Alexander. The first husband. I'm here to crash the wedding!'

“Britney Spears invited me here. She’s my first wife—my only wife. I’m her first husband. he said during the live video on Instagram.

As Alexander descends a hillside, he enters the wedding tent where planners were there, even shaking hands with some of the workers.

He then marches inside the house demanding to know: 'Where's Britney?' and  Alexander was apprehended by security and pinned to the ground.

Alexander was arrested on an outstanding warrant not for criminal trespass without permission entering someone house.

Britney’s attorney, Matthew Rosengart, told Page Six that he wants Jason prosecuted for breaking into the star’s home.

He added, “I’m working closely with law enforcement to ensure Mr. Alexander is aggressively prosecuted to the fullest extent of the law.”
