Spears and Alexander got married in Las Vegas in 2004, but had the marriage annulled 55 hours later.
Alexander live streamed himself approaching Spears’ house on Instagram. The footage was obtained by TMZ, who first broke the story. He made it inside the home, and told security that Spears had invited him. Then, he began shouting for Britney.
In another part of the video, Alexander is outside and asks someone else, “Where’s Britney?”
“I’m Jason, her first husband. I’m here to crash the wedding,” he says. He then makes it inside a tent that appears to be set up for the wedding ceremony. He continues to tell people who he is and that Spears invited him – although he also admits he’s there to crash the wedding.
Officers eventually detained him and his live stream cut out. TMZ also obtained a photo of officers detaining Alexander on the ground.
Earlier in the day, Alexander posted a video on Instagram calling for everyone in Spears’ life to be investigated.
In 2020, fans spotted Alexander at a “Free Britney” rally when the pop start was fighting to end her conservatorship.
