JON & JANUARY’S SECRET HOOK-UPS

Mad Men co-stars Jon Hamm and January Jones have refuelled long-running rumours of an affair by meeting up in secret in their LA neighbourhood.

“They’re very private people [but] everyone who knows them believes they’ve been sleeping together on a casual basis for years, and locals in Los Feliz have seen them sneaking around together,” reveals an insider.

Sources believe Jon, 47, began hooking up with his 40-year-old on-screen wife after splitting from his girlfriend of 18 years Jennifer Westfeldt in 2015. “There’s always been a spark between Jon and January,” adds the source. “When he broke up with Jennifer, that opened the door for them to become more than friends.”
