The ruggedly handsome Mad Men star was spotted dining out with long-term partner Jennifer Westfeldt, 43, on-screen wife Jessica Pare and 30 Rock actor Jack McBrayer at trendy Los Angeles eatery Little Dom’s on Saturday.
But, despite the star-studded company, Hamm only had eyes for his screenwriter girlfriend.
“It was Jon’s birthday and he had a modest gathering of famous friends in attendance,” an eyewitness tells Radar.
“In fact, despite all the others around them, they were literally gazing into each other’s eyes as they sat at the table.
“Jack was with them, and Jessica joined the party later to pass on her best wishes, but even she couldn’t distract Jon from Jennifer!
“They were the picture of happiness and seemed to be having a super chill time,” the onlooker reveals.
As RadarOnline.com previously reported, Jon and Jennifer met at a mutual friend’s party in L.A. more than 14-years ago — and, despite their obvious happiness (or maybe, because of it!!) the couple has zero plans to marry.
In an interview with Parade magazine in 2010, Hamm revealed that he was missing the “marriage chip.”
“Neither of us have the greatest examples of marriages in our families,” he explained. “But Jen is the love of my life, and we've already been together four times longer than my parents were married.”
Meanwhile, it's pretty much guaranteed that Donald Draper will also be setting a bad example for married life when the sixth season of Mad Men kicks off with a two-hour special on AMC, April 7.
