It's official! After 18 years of dating -- and many breakup rumors -- Jon Hamm and Jennifer Westfeldt announced today that they have called it quits for good.
"With great sadness, we have decided to separate, after 18 years of love and shared history," the couple told PEOPLE in a joint statement. "We will continue to be supportive of each other in every way possible moving forward."
As Radar reported, breakup rumors had swirled for weeks, with sources saying Westfeldt, 45, had been pressuring Hamm, 44, to start a family. Ultimately, an insider told Star magazine in early July, the relationship "had just run its course."
