Jon Hamm And Jennifer Westfeldt Squash Split Rumors

One of Hollywood's most durable couples won't be calling it quits anytime soon.

At least according to a rep for Mad Men star Jon Hamm, who says that he and girlfriend Jennifer Westfeldt are still together after 16 years, despite a published report by In Touch magazine.

"The only gentleman Jennifer visited regularly in Connecticut was Jon, while he was in rehab," the rep said in a statement to E! News. "They continue to ask for the public's understanding and sensitivity during this challenging time."

Hamm recently completed a month's stay at the Silver Hill Hospital in New Haven, CT, where he had been undergoing treatment for alcohol abuse. In Touch reported that Hamm and Westfeldt split before his treatment, but remained friendly.

News of Hamm's stay in rehab didn't go public until he began doing publicity for the second half of Mad Men's final season.
