Jon Hamm and his longtime girlfriend, Kissing Jessica Stein writer Jennifer Westfeldt, announced their split on Monday after 18 years together, People reports. The couple, who never married, were last seen together at the premiere party for Wet Hot American Summer: First Day of Camp on July 22, where they appeared as affectionate as ever.
“With great sadness, we have decided to separate, after 18 years of love and shared history,” the couple tells PEOPLE in a joint statement. “We will continue to be supportive of each other in every way possible moving forward.”
Eighteen years is an eternity when it comes to celebrity relationships, and after having survived Hamm’s rise to become one of Hollywood’s notoriously handsome and desired leading men — not to mention his recent stint in rehab — you’d think the two of them could get through anything. Very sad news indeed.
