The mystery guy appears to be 29-year-old Chicago resident Ben Hanisch, who posted a sweet picture with Amy on New Year's Eve and captioned the snap, "Sometimes in life you get extremely lucky, and the smartest, funniest, most beautiful woman comes along when you least expect it. Here's to what adventures 2016 brings!"
Amy hilariously left a comment on the photo, "I'm pregnant. I didn't know how else to tell you."
ET has reached out to Amy's rep.
A source told People that Ben is a furniture designer, and "Amy is so, so happy" about the reported relationship.
“She calls him her boyfriend and says he constantly tells her how pretty, sexy and perfect she is. She feels like she hit the jackpot," the source added. "Her sister loves him and that's important because her and her sis are BFF."
The 34-year-old actress has talked about her dating life in the past. Last October, Amy told The Insider the specific things she looks for in an ideal guy.
"He has to be funny, he has to be nice, and he has to have a normal relationship with his mother," she revealed at the time.
Surprisingly, Amy also said that the quality of her suitors had "absolutely not" gone up, even during her remarkable year, which included an HBO stand-up special and Trainwreck, which this weekend is vying for two Gloden Globes, including a Best Actress in a Comedy nom for Amy herself.
