Jason Alexander, who was briefly married to Spears in 2004 for a grand total of 55 hours, live streamed his efforts to disrupt the wedding on Instagram.
It has since been ruled by Ventura County Judge David Worley that there is sufficient evidence for Alexander to go on trial for alleged stalking.
This is everything you need to know.
Who is Jason Alexander?
Jason Alexander was a childhood friend of Spears, who grew up with the singer in Louisiana before she became a worldwide celebrity.
Alexander was Spears’ first husband, a childhood friend whom she married in January 2004 at the Little White Wedding Chapel in Las Vegas, Nevada. At the time, both Spears and Alexander were 22-years-old.
However, after 55 hours of married life, Spears filed for annulment, stating in the petition that she “lacked understanding of her actions to the extent that she was incapable of agreeing to the marriage”.
Their marriage was quickly annulled, with Spears’ attorney at the time, David Chesnoff, saying: “There is no marriage now.
“Jason agreed to this completely. They’ve made a wise decision. I know they care about each other. They are friends.”
Talking to Access Hollywood in an interview after the annulment, Alexander said: “It was just crazy, man.
“We were just looking at each other and said, “Let’s do something wild, crazy. Let’s go get married, just for the hell of it”.”
In the months after dissolving their marriage, Spears told E! that the marriage was just her “being silly”.
She said: “It was me being silly, being rebellious, and not really taking the responsibility of what I was doing, you know?
“And after partying, you know, you really don’t think about what you’re doing. So it was one of those things that were really silly.”
In July 2021, Alexander spoke further about the marriage in an episode of Toxic: The Britney Spears Story podcast, where he claimed that Spears had asked him to get married in a spur of the moment conversation.
He said: “We felt like this was a way that would bond us together, regardless of how far we are separated. We’re married. You can’t not let us reunite.”
Alexander claimed that, after the wedding at the chapel, they “consummated the marriage in the limousine on the way back to the hotel”.
He said: “Then we got back to the hotel, “Hey, guess what? We’re married!” and everybody freaked out and no one was happy. And I was like, “Oh, this is about to get interesting”.”
Alexander then continued on to say that he felt he was tricked into going through with the annulment.
He said: “So we were talking every day and I still believed the story I was told, that they were going to let us continue to talk and then we would have this marriage in the future if we felt the same way.”
He claimed that he was told he could remain in a relationship with Spears after the annulment was confirmed, and explained that his lawyers had said that he had 30 days to contest the annulment.
However, when those 30 days were up, he claimed that Spears’ phone number was suddenly no longer in service.
What happened at Britney Spears’ wedding?
On the day of Spears and Aghari’s wedding on Thursday 9 June, Alexander turned up at Spears’ home in Los Angeles where they were getting married.
He began live streaming on Instagram and, approaching the security, said that Spears had invited him to the event.
He said: “[Spears] is my first wife, my only wife. I’m her first husband. I’m here to crash the wedding.”
After a struggle with security, Alexander was able to make it inside Spears’ home, where he continued to live stream from his phone.
Richard Eubler, a since-fired security guard for Spears, testified that Alexander got inside her house and up to the locked door of Spears’ bedroom while she was inside.
The ex-guard said Alexander had also tried to enter the property in the days before the wedding.
Eventually Alexander was restrained and then arrested by officers from the Ventura County Sheriff’s Department who responded to an incident of alleged trespassing.
The day after the wedding, Spears and Asghari obtained an emergency protective order in court against Alexander, according to Spears’ lawyer Mathew Rosengart.
What has he been charged with?
Alexander has been charged with felony stalking following the incident at Spears’ wedding at her home in Los Angeles.
He pleaded not guilty to the charge as well as four misdemeanours at a court in Ventura County on Monday.
He faced two counts of misdemeanour battery, one count of misdemeanour vandalism and and one count of misdemeanour trespassing.
Speaking to the PA news agency at the time of Alexander’s arrest, Sergeant Cyrus Zadeh said that during an altercation with security officers, items had been broken.
Zadeh said: “[Alexander] was able to find his way onto the property and was confronted by security.
“An altercation occurred with the security officers and that’s where the battery occurred… and during the altercation an item was broken so that’s where the vandalism comes into play.
“And by being on private property, the trespass comes into play.”
Attending his hearing virtually via video conference, Alexander had his bail set at $100,000 (£82,000) and was issued a restraining order requiring him to stay at least 100 yards from Spears for three years.
A judge has found there is sufficient evidence for Alexander to go on trial for alleged stalking.
After a two-hour preliminary hearing, Ventura County Judge David Worley ruled that Alexander should be held to answer on the charge, along with misdemeanor counts of trespassing, vandalism and battery, court records showed.
Not guilty pleas to all the charges were entered by an attorney for Alexander, who did not attend and remains imprisoned.
Alexander’s attorney, Sandra Bisignani, argued there was no evidence he had any intention of harming Spears.
