Britney Spears' ex-husband and childhood friend Jason Alexander attended a 'Free Britney' protest during her conservatorship hearing

• Britney Spears' ex-husband joined protests over her conservatorship outside of a courthouse in Los Angeles on Wednesday.
• Ahead of her hearing, Spears had petitioned to get her father, Jamie, off of the conservatorship that has given him power over her finances and personal life for 12 years.
• In interviews outside the courthouse, Jason Alexander claimed that he spoke to Spears on the phone Tuesday night and went to the protest to show his support.
• Spears married her childhood friend Alexander in 2004 in Las Vegas, but the marriage was annulled 55 hours later.

The ex-husband of Britney Spears, who was famously married to the pop icon for only 55 hours, attended the #FreeBritney protest outside of her conservatorship hearing in Los Angeles on Wednesday.

Jason Alexander was among the members of the grassroots movement calling for an end to Spears' court-ordered conservatorship outside of the Stanley Mosk Courthouse.

Spears' father, Jamie Spears, has been the conservator aspects of his daughter's financial and personal life since 2008, after the singer's public mental health battles. 12 years later, the conservatorship remains, and thousands of people have joined together online to fight for an end to the conservatorship, which many speculate is not necessary.

Outrage over the conservatorship has grown on social media in recent months, as celebrities including Paris Hilton and Rose McGowan have posted about it.

Ahead of Wednesday's hearing, Spears was reportedly petitioning to get her father off of the conservatorship. Court documents obtained by CNN said that "Britney is strongly opposed to having James [Jamie Spears] as conservator of her person."

Alexander claimed in an interview at the protest that was live-streamed on Instagram by podcaster Drew Plotkin that he spoke with Spears on the phone Tuesday night, and he was there to support her. "She definitely wants her dad out of the picture as far as the conservatorship," Alexander said in Plotkin's Instagram Live.

In 2010, after Alexander confirmed the authenticity of a leaked recording of him and Spears to Radar Online, Spears tweeted that he could "kiss my lily white southern Louisiana a-s!"

Spears married her childhood friend Alexander, whom she grew up with in Kentwood, Lousiana, in January 2004 during a trip to Las Vegas. The marriage was annulled 55 hours later.
