2015: The Summer of Splits

From Gigi Hadid and Cody Simpson in May to Jon Hamm and Jennifer Westfeldt in September, here at the 16 couples who called it quits during the summer of 2015. Here's hoping the fall will be a lot less heartbreaking

GWEN STEFANI AND GAVIN ROSSDALE

They met when their respective bands, No Doubt and Bush, toured together way back in 1995. And now – after 20 years together and nearly 13 years of marriage – Hollywood's coolest couple have called it quits. The pair has three sons, whom they remain committed to raising in a "happy and healthy environment," they told PEOPLE in a statement. The couple were always candid about the ups and downs of marriage: "My biggest accomplishment is my marriage so far," Stefani said in 2012. "Because it's hard, everyone knows it's hard. [It] is something that I always wanted to do successfully. It was a dream of mine."
