Britney Spears Gets Married! Parents, Sister and Sons Weren't There, But These Celebs Were

The two said "I do" at the couple's Thousand Oaks home.

Even though it was an intimate affair, Spears and her new husband did have some A-list celebrities in attendance, including Donatella Versace, whom Britney previously called the "mastermind" behind her gorgeous white dress.

Donatella shared video of the stunning gown to Instagram on Friday:

Drew Barrymore, Madonna, Selena Gomez, Maria Menounos, Ansel Elgort, will.i.am, Paris Hilton, and her mom Kathy were among the 60 or so total guests, per photos from the ceremony posted at TMZ. Versace shared a short video to her Instagram Stories of her making her way to a limousine in black -- while Paris showed off a look at her outfit for the big day on Instagram as well (gallery below).

Speaking to Vogue, Spears said the couple wanted "warm and feminine colors including blush, white, cream, and gold, and a lot of various shades of pinks, blush, and reds" for their special day. "We really wanted to make this a small and beautiful moment with family and friends," she added."

After the ceremony, Asghari's manager Brandon Cohen, told People, "I am very ecstatic this day has come, and they are married. I know he wanted this for so long. He is so caring and supportive every step of the way."

According to People, Spears walked down the aisle to Elvis Presley's "Can't Help Falling in Love." The ceremony itself, per Vogue, lasted just 10 minutes.

At the after-party, Spears changed into a red mini-dress, again from Versace. The couple reportedly didn't have a first dance, but Britney, Madonna and Selena all danced together to "Toxic," before Britney and Paris sang "Stars Are Blind." The newlyweds left in a Rolls Royce with "Just Married" on the back around 10:15pm.

There was some major drama at the house hours before the ceremony, however.

Streaming live on Instagram, Spears' first husband, Jason Alexander, surprised her security -- and pretty much everyone else -- when he tried to crash the wedding at her home, per TMZ, shouting that Spears was his first and only wife and even insisting she'd invited him.

TMZ additionally reports that Alexander was arrested and booked for trespassing, vandalism and two charges of battery for getting physical with Spears' security. The outlet says he remains in custody at this time.

It seems pretty unlikely that Alexander had an invitation, though, when you consider who else in Spears' life didn't have one. Her sons with Kevin Federline, 16-year-old Sean Preston and 15-year-old Jayden James were not  in attendance, and neither were here parents, Lynne and Jamie, or her younger sister, Jamie Lynn.

While Spears' sons opted out of attending, per several media outlets, Federline's attorney told TMZ that Federline and the boys "are happy for Britney and wish her and Sam all the best going forward."

Spears has not been shy in expressing her frustration and outright anger at her family as she fought and ultimately secured her independence out from under a conservatorship that had come to dominate her life and professional career.
