Ahead of the festivities, an insider revealed Spears, 40, had been envisioning her wedding day for nearly nine months.

"Britney started planning and dreaming about her wedding shortly after she got engaged in November," the insider said. "It's a huge deal to her that she is finally able to get married. She wants it to be perfect."

Her sons Sean Preston, 16, and Jayden James, 15, were not in attendance at the wedding but are "happy" for their mom, a lawyer for Kevin Federline told PEOPLE on Thursday.

Spears and Asghari were first romantically linked after they met on set of the singer's "Slumber Party" music video. Spears later revealed in a radio interview in 2017 that she and Asghari, 28, took nearly "five months" to reconnect after her video shoot.

"I was like, 'He was really cute, this guy was really cute,' so I called him," she said about digging up his phone number. "He's just a really fun, funny person."

Fast forward and the couple announced their engagement last September, months before her conservatorship was terminated in November. At the time, Asghari's manager Brandon Cohen told PEOPLE that he is "proud to celebrate and confirm the engagement."

"Britney is ecstatic," a source told PEOPLE after Asghari popped the question at her Los Angeles home.

In February, the couple added their Australian Shepherd puppy Sawyer to the family. "Geez .... can you have two loves of your lives because he comes in second !!!!" Spears wrote on Instagram at the time.

Last month, Spears gave fans a peek at her wedding-day look while introducing her new cat Wendy.

"Introducing Wendy 🐈 !!! And yes, this is the veil to my wedding dress 👰🏼‍♀️ !!!" Spears wrote alongside a snapshot of the feline sitting atop white tulle fabric.

"Our lives has [sic] been a real fairytale. Happy Mother's Day to you my soon to be queen," wrote Asghari. Apparently alluding to their nuptials, he continued, "Also the big day has been set! But nobody will know until the day after."
