Schumer and Fischer exchanged vows in front of about 80 people, including Jennifer Aniston, Jake Gyllenhaal, Jennifer Lawrence, Larry David and David Spade. On Thursday, Schumer shared photos from the event on her Instagram. The bride wore a Monique Lhuillier gown picked just four days before the ceremony, her stylist tells PEOPLE.

The announcement comes just days after the Trainwreck star and chef made their relationship social-media official with a kissing photo on Instagram Sunday.

“Happy Birthday @theellenshow thank you for having us!” the 36-year-old actress wrote alongside a romantic black-and-white picture of the pair sharing a smooch, which was presumably taken during taken during Ellen DeGeneres’ star-studded birthday bash on Saturday.

Relationship rumors began swirling around Schumer and the chef and cookbook author after they were photographed together in November of last year, chatting over a dinner in New York City. Schumer’s rep declined to comment on whether their relationship was romantic at the time.

The pair were most recently spotted together in New York in January, as they arrived at NBC Studios to watch Saturday Night Live, which marked only the second time they had been seen in public together.
