Jon Hamm, Jennifer Westfeldt Break Up [RUMORS] After ‘Mad Men’ Final Season Premiere: Split Because of Alcohol Abuse?

Let's hope the rumors are false, folks. It's being reported that Mad Men's very own Jon Hamm – who has starred as Don Draper throughout the AMC series' entirety, even for the final season premiere that aired this past Sunday – and his longtime girlfriend Jennifer Westfelt have called it quits. The two have been together for 18 years, and some have said Hamm was dumped by his girlfriend before he entered New Canaan, Connecticut's Silver Hill Hospital for alcohol rehabilitation.

The speculation comes from The Daily Mail, who admit that while they've reached out to Hamm's people, no one has immediately responded. They claim, howevever, that the actor was "given the boot" before heading on into the Connecticut rehab.

Of course, another report from In Touch Weekly notes that the longtime couple called it quits due to "a lack of commitment" from Hamm himself. A source said, "She told him it was over before he checked into rehab. ... She was tired of waiting for a commitment from Jon."

Despite the breakup, word has it that the two are remaining friends.

"Jennifer wants a life that Jon can't give her," In Touch's source says. "People are happy for her and hoping she never takes him back."

Whoa ... harsh.

Hamm, of course, recently celebrated the premiere of Mad Men's final season. Take a look at an MStars News recap of the premiere episode (of the final season).

So, readers, what will be harder: letting go of Don Draper and letting go of this once-upon-a-time couple?
