Britney Spears and Sam Asghari Signed a Prenup Confirming He Won't Receive Any of Her Past Earnings

Britney Spears is making sure her assets are protected in her new marriage to Sam Asghari.

The newlyweds have signed a prenup ensuring that Asghari, 28, will not receive any of Spears' multi-million dollar fortune earned before the wedding date in the event that they split in the future, PEOPLE confirms. TMZ was first to report the news.

Spears, 40, and Asghari tied the knot at the "...Baby One More Time" singer's home in Los Angeles, California, on Thursday night, where they said "I do" in front of 60 guests.

During the ceremony, Spears walked down the aisle in a custom Atelier Versace, before changing outfits three more times throughout the night.

Among those in attendance included Drew Barrymore, Madonna, Paris Hilton and Selena Gomez, to name a few.

Shortly after the couple announced their engagement in September, Asghari took to Instagram and joked about needing a prenup to protect his own belongings — which clearly aren't worth as much financially as Spears' earnings.

"Thank you everyone who is concerned about The prenup!" the actor and fitness instructor wrote on his Instagram Story. "Of course we're getting an iron clad prenup to protect my jeep and shoe collection incase she dumps me one day."
