Britney Spears' ex-husband of 55 hours attended the pro-Trump protest in DC before rioters stormed the Capitol

• Britney Spears' ex-husband Jason Alexander, whom she was married to for 55 days in 2004, attended the pro-Trump protest in Washington, DC, on Wednesday.
• It's unclear if Jason Alexander was part of the riot that stormed the Capitol building.
• He posted a selfie from DC on his Facebook, which also includes posts featuring anti-mask rhetoric and false claims that the 2020 presidential election was stolen from President Donald Trump.

Britney Spears' first ex-husband, a childhood friend who she married for 55 hours in 2004, attended the protest in support of President Donald Trump in Washington, DC, which descended into a riot as attendees stormed the Capitol on Wednesday afternoon.

It's unclear if Spears' ex, Jason Allen Alexander, was one of the rioters who stormed the Capitol as lawmakers were counting Electoral College votes, but he posted a selfie on Facebook showing he was at the event.

"DC. Millions showed up," he wrote as a caption for a selfie he posted from Washington, where thousands of Trump supporters falsely claimed the 2020 election was stolen from the president through fraudulent votes.

The photo Alexander posted featured him wearing a Trump winter hat with the number 45 embroidered on the front.

Alexander's Facebook also features public posts about not wearing masks during the COVID-19 pandemic, and a job description in which he says he's a "journalist researcher at Conspiracy Theories & History."

He did not immediately respond to Insider's request for comment.

Spears married Alexander, who she grew up with in Kentwood, Louisiana, during a trip to Las Vegas in January 2004. Their marriage was annulled 55 hours later.

He attended a #FreeBritney protest in support of Spears last year, calling for an end to Spears' court-ordered conservatorship, also known as a legal guardianship.

Spears has been the subject of the conservatorship since 2008, when her father was made the conservator of her personal and financial life amid her public health issues. Under the conservatorship, Spears has no control of her financial or personal decisions.

In an interview at last year's protest that was live-streamed on Instagram by podcaster Drew Plotkin, Alexander said he had spoken to Spears days earlier.

It's unclear if Spears and Alexander are still in touch.
