• Britney Spears and longtime boyfriend Sam Asghari are reportedly getting married Thursday night. 
  • Hours before the ceremony, Jason Allen Alexander (who wed Spears in 2004) arrived uninvited.
  • Ventura Police confirmed to Insider that the arrest happened at the venue.

Sheriff's deputies have arrested Jason Allen Alexander — a man who was married to Britney Spears for 55 hours in 2004 — after Alexander arrived uninvited to Spears' wedding at her home in Thousand Oaks, California.

The Ventura County Sheriff's Department confirmed the incident to Insider, noting that an arrest happened at the venue and the investigation is ongoing. 

Earlier today, news broke that Spears and her fiancé Sam Asghari were set to marry on Thursday night at the pop star's mansion. 

The news was reported on Thursday as paparazzi images of a wedding tent emerged from Spears' home in Thousand Oaks — a city north of the Los Angeles, California area. 

People magazine reports that Spears' parents, Jamie and Lynne Spears, along with her younger sister Jamie Lynne, a namesake of her parents, were not included in the celebration.

Over the last year, both of Spears' parents and her younger sister were the subject of much scrutiny as the singer's conservatorship battle raged on.

After the legal guardianship, which her father Jamie had overseen for 13 years, was terminated last November, Spears frequently posted Instagram captions and stories about her experience of alleged abuse at the hands of her family, including feelings of ire towards her little sister's memoir.

Spears has two sons from a previous marriage to Kevin Federline: Sean Preston, 16, and Jayden James, 15. According to People, neither of her sons will attend the wedding.

"They're happy for their mom and they are hopeful that Sam and Britney are starting a great future together," Federline's lawyer told People. "It's their night and they didn't want to take away from them."

Spears and Asghari got engaged in September 2021, a couple of months before a Los Angeles judge ruled in favor of terminating the conservatorship. 

In April 2022, Spears and Asghari announced they were expecting their first child together. About a month later, Spears revealed on Instagram that she had miscarried and was no longer pregnant. 

Asghari made a rare public statement about his relationship with Spears and the miscarriage in a profile interview for GQ.

"It's something that happens to a lot of people," the 28-year-old actor and personal trainer said. "A beautiful thing somebody had said was, it's a common process and the female body is just so amazing, and just the human body in general is so beautiful that it heals itself. And that when the baby's ready it'll be the right time."
