The pop superstar tied the knot with Sam Asghari as planned on Thursday evening, a source close to Spears confirms
The intimate ceremony took place at her home in Thousand Oaks. She wore a custom Versace dress.
The pair, who got engaged in September 2021, first met in 2016 when Asghari co-starred with Spears in the video to her single, "Slumber Party."
"It was the most spectacular day," Spears wrote. "I was so nervous all morning but then at 2:00 pm it really hit me ... WE'RE GETTING MARRIED!!! I had a panic attack and then got it together."
She thanked those involved with planning her big day for turning her home "into literally a dream castle."
Prior to the ceremony on Thursday, Spears' ex-husband, Jason Alexander, was arrested and charged with trespassing and battery after gaining unauthorized access to the wedding site, according to police.
Ventura County Sheriff's deputies were called to the residence in response to a trespassing report, according to police.
The trespassing suspect was later identified as Alexander, according to Sgt. Cyrus Zadeh with the county sheriff's office.
Alexander was confronted by security when he entered the singer's property, and an altercation ensued between him and two security officers
