Jennifer Westfeldt and Jon Hamm, one of Hollywood’s longest-running committed-but-not- celebrity couples that were married, have called it quits.

Hamm, 44, and Westfeldt, 45, said in a joint statement, “With great sadness, we’ve decided to split, after 18 years of love and shared history.”

My life has additionally gone in a million ways I never expected.

“And we have a fairly great life together,” she continued.

With All the couple somewhat often represented over the years as husband and wife, Hamm was pressed to describe his views on union in an 2014 Playboy interview.

He said tying the knot was “Never a discussion” between him and Westfeldt.

“I believe union frequently is an arrangement between families more than an arrangement involving the two people involved,” he told the magazine.

“I don’t have a specially defined example of union in my life.”

Ben Affleck and Jennifer Garner appear happy – just not happily-ever-after.
