The two were married at a house in Malibu, California, in front of 80 friends, including stars Larry David, Jennifer Aniston, Jennifer Lawrence, David Spade and Jake Gyllenhaal, according to People and Us Weekly.
Schumer confirmed her nuptials after the news broke, posting wedding photos on Instagram and writing simply, "Yup."
The comedian with actress Jennifer Lawrence:
Schumer later posted a message on Instagram saying that she wasn't pregnant, and that she wanted people to donate to the gun-control advocacy group Everytown for Gun Safety in lieu of wedding gifts.
Schumer, 36, and her chef boyfriend made their relationship public (as in Instagram-official) this week after attending Ellen DeGeneres' star-studded birthday party. The two reportedly started dating around November after they were spotted having an intimate dinner in New York City.
They later attended a taping of "Saturday Night Live" together, though Schumer's rep wouldn't comment on the relationship.
Fisher once worked at Mario Batali's New York City restaurant, Babbo, after being introduced by his friend, Jake Gyllenhaal.
The chef later returned to Martha's Vineyard, Massachusetts, where he grew up, to work at the Beach Plum Inn (a favorite of the Obamas) and The Covington Restaurant.
Fisher ― who penned the James Beard Award-winning cookbook, Beetlebung Farm Cookbook ― recently opened Beetlebung Farm Market on Martha's Vineyard, and plans to turn part of it into a restaurant.
"After years of working for other people, my intuition is, 'I'm doing this on my own terms,'" Fisher told Boston magazine in July. "You can create a destination restaurant anywhere."
Prior to meeting Fischer, Schumer dated furniture designer Ben Hanisch. The two met on a dating app in 2015 and were together for a little over a year.
"I feel like Ben is the first guy who's really been my boyfriend," the "I Feel Pretty" actress and author told Marie Claire in July 2016. "There are guys who, if they heard me say that, would want to punch me in the face, but yeah, it's the truth."
A rep for Schumer confirmed that she and Hanisch split in 2017, but said the two remained friends. It certainly seems like things are amicable, as the comedian thanked her ex for some furniture he'd built for her in September.
