See: Did Mel B know about husband Stephen Belafonte's dinner date with another woman?
The former Spicer Girl cited "irreconcilable differences" as the reason for their alleged split, according to USA reports.
Mel B has apparently "filed for divorce" from husband Stephan Belafonte.
According to People, the Spice Girl and America's Got Talent judge listed December 28 as the date of separation on the divorce papers and requested joint legal and physical custody of the 5-year-old couple's daughter, Madison Brown Belfonte.
The "America's Got Talent" judge also reportedly requested that the court not be able to award spousal support.
This is 41-year-old Mel's second divorce, having split with Dutch dancer Jimmy Gulzar in 2000.
The Spice Girl married Hollywood producer Stephen Belafonte after a five-month whirlwind romance in 2007.
"We have been through everything that would normally tear couples apart and we have come out on the other side stronger", she wrote.
Last year, Brown hit back at tabloid rumours about their relationship, saying they "will be together forever".
Both were by their dad Martin's bedside when he passed away after a long battle with cancer earlier this month and Mel signed off a touching Insta tribute to the 63-year-old as being from both of them.
Belafonte also has a child from his relationship with ex-girlfriend Nicole Contreras, a 12-year-old daughter named Giselle.
Representatives for Mel could not be immediately reached.
