The pair announced their engagement nine months after first being seen dating. They tied the knot six months after that, in May of 2015 in St. Mary's Church at Woburn in southern England.
Horner recently spoke about the cross-entertainment relationship.
"Life works in mysterious ways," Horner told The Telegraph. "I didn't marry Geri because she's a Spice Girl. I married her because I fell in love with her. It will be ten years this time next year, and we've been happily married for seven. We're very different characters, but we complement each other well."
