ITV News Correspondent Hamish Auskerry reports on Britney Spears' wedding
Spears was pictured with fellow celebrities Madonna, Selena Gomez, Drew Barrymore, Paris Hilton and Donatella Versace at the ceremony.
Around 60 guests were said to have been invited and Spears wore a sleek, off-the-shoulder white dress for the ceremony.
Her former husband Jason Alexander had attempted to crash the wedding, but was arrested after making his way onto the property.
Spears, 40, said she wanted her wedding to Asghari, a 28-year-old fitness trainer, to be a “small and beautiful moment with family and friends”.
The star arrived in a horse-drawn carriage before walking herself down the aisle, according to reports.
A source told American outlet People that Elvis Presley’s Can’t Help Falling in Love played as the bride walked solo down the aisle.The Toxic singer told Vogue magazine: “We really wanted to make this a small and beautiful moment with family and friends.
“We wanted warm and feminine colours including blush, white, cream, and gold, and a lot of various shades of pinks, blush, and reds.”

The pair became engaged in September last year, with Spears joking that the proposal was “way overdue”.
The singer previously said her 13-year conservatorship, which ended last year, did not allow her to marry or have a baby.
In May, Spears announced a miscarriage, mourning the loss of her "miracle baby" in an Instagram post.
Thursday was her third trip to the altar, having divorced Kevin Federline in 2007 and Mr Alexander in 2004, after their marriage earlier that year.
The house's exterior was adorned with flowers for the wedding and Spears changed into a red minidress after the ceremony. According to TMZ, Spears' brother Bryan attended the ceremony but her sister Jamie-Lynn and parents were not present.
Spears has been estranged from her parents and sister after she was placed under the controversial conservatorship in 2008. The arrangement controlled many aspects of her life, including her finances, amid substance abuse and mental health issues.
