Mad Men star and longtime girlfriend call it quits
Another celebrity couple have parted ways.
US actors Jon Hamm, 44, and Jennifer Westfeldt, 45, released a statement on Monday that said they were separating after 18 years together "with great sadness".
The pair, who never married, added they would "continue to be supportive of each other in every way possible".
Earlier this year, the Mad Men TV star completed rehab for alcohol abuse and credited Westfeldt for supporting him throughout his treatment.
