The former Spice Girl and America’s Got Talent judge reportedly filed divorce papers at the Los Angeles Superior Court on Monday, obtained by E! News.
According to the US website, the 41-year-old is requesting joint custody of the couple’s six-year-old daughter, Madison, but is seeking to terminate spousal support.
The court papers state that the pair separated on December 28 2016, despite the fact that they have posted pictures of each other on their social media accounts this year.
Last month the pop star posted an Instagram snap of the pair, under the caption: “My baby boo @stephenthinks11.
“We have been through everything that would normally tear couples apart and we have come out on the other side stronger,you loved me before I even new how to really love myself,you are my world honey and let's not forget you are abit of a d******* too xxxx (sic).”
The couple tied the knot in a secret ceremony in Las Vegas back in June 2007 having dated for just five months.
Just one year later they renewed their vows in front of friends and family at a ceremony in Egypt, welcoming their daughter three years later.
They have been plagued by rumours of a tumultuous relationship for the last few years with both vehemently denying allegations of domestic abuse.
