The daughter of NBC news anchor Brian Williams met the College Humor co-founder, 33, through mutual friends and told Glamour earlier this month that she would “walk away from” her career in order to have kids.

“I’d love to be a mom – and not have to bring my kids into my trailer Or a balance [of both],” said Williams, who plays Marnie on the hit HBO show. “But you’ve [got to] call it on the fly to a certain extent.”

In an interview with Larry King in January, Williams admitted that her boyfriend and friends were getting used to her newfound fame, and were “very good at taking cell phone pictures” with fans.
