The "Trainwreck" star shared the photos from her wedding to Fischer, who is a chef, on her official Instagram page.
The actor also clarified that she is not pregnant and asked fans to donate to the non-profit Everytown for Gun Safety instead of sending her gifts.
"2 things. No I'm not pregnant. And no gifts but thank you for asking. Instead please consider donation to Everytown for Gun Safety.
"Thought of Mayce and Jillian a lot yesterday and sending love to everyone who has been affected by gun violence," Schumer said in the post.
