Late last week, Britney Spears tied the knot with her partner of six years, Sam Asghari.

While we've seen glimpses of the big day via Britney's Instagram, beyond the pictures, a certain amount of controversy has surrounded the happy couple.

From wedding snubs to wedding crashers and false claims from the Spears' family themselves, here's everything we know about the singer's nuptials.

Childhood friend and ex-husband gatecrashed the wedding.

Britney Spears' ex-husband gatecrashed her wedding – and aired the whole thing via an Instagram live video.

Jason Alexander, who was married to Spears for 55 days, filmed himself entering her Los Angeles home where the wedding took place last week.

In the Instagram video shared by TMZ, Alexander approached a security guard who told him he needed to leave.

"I'm here to crash the wedding," he said in the video as he made his way around the property.

"She's my first wife, my only wife. I'm her first husband."

An altercation then reportedly takes place before his phone froze.

According to the Associated Press, officers responded to a trespassing call after 2pm local time and detained Alexander.

Ventura County Sheriff’s Capt. Cameron Henderson confirmed Alexander was then arrested after officers noticed he had a warrant for his arrest in another county, the publication reports.

Spears, who had her conservatorship dropped last year, tied the knot in an intimate ceremony with her partner of six years and personal trainer Sam Asghari.

Alexander pleaded not guilty in Ventura County court after being charged with felony stalking, along with misdemeanour counts of trespassing, vandalism and battery.

Britney Spears' calls out brother, Bryan Spears.

The singer spoke out against her brother on Tuesday, pointing out that her brother Bryan Spears was not invited to her wedding, despite claims that he was.

In the now-deleted post to Instagram, Spears called out her brother, telling him, "your podcast interview was so SPECIAL [eye roll Emoji]!!! ... When asked by that incredibly kind man 'why doesn't your family just let her be ???' Your response was ... 'she can't even make a dinner reservation' ..."

Spears seemed to be referencing her brother's appearance on the podcast back in 2020 – over a year before her conservatorship officially ended.

"I know what she wants, but at the end of the day what is the reality of that?" he said at the time when Spears made clear she was ready for her conservatorship to end.

The singer went on to say, "What you said right there to that man in that interview said everything, Bryan !!! You were never invited to my wedding [bride Emoji] so why even respond ???"

She added, "Psss I have an assistant to make my dinner reservations ..."

The response from Spears followed swiftly after her brother's girlfriend, Amber Lynn Conklin, claimed she and her partner did not attend the celebrity wedding due to his 11-year-old daughter's elementary school graduation falling on the same day.

Conklin wrote that he felt "terrible," but "couldn't help the timing".

"...He felt terrible having to choose, but he had to be there for his daughter and sent his love to Britney x1000000 [three heart Emojis]. We are so sad to miss such an important moment but so so happy for Britney and Sam's Marriage!" she wrote, according to PEOPLE.
