Comedian Amy Schumer and her boyfriend, chef and author Chris Fischer, married in the US on Tuesday.

The Trainwreck star shared her happy news on Instagram after reports of her nuptials in the US media.

American publication Us Weekly, which first reported the story, said the wedding took place in a rented house overlooking the ocean in Malibu, California with Jennifer Lawrence, Jennifer Aniston, Larry David, David Spade and Judd Apatow in attendance. 

"It was a very chill wedding. It was thrown together last minute," one source told Us Weekly

"Most of the guests found out the wedding was happening on Tuesday from a text message sent out by Amy on Sunday. It was like, 'Hey, this is happening. If you can make it, great. If not, no worries'.

"It was a gorgeous day. Everyone was having a good time," the source added.

Schumer and Fischer are reported to have begun dating last year, with the star confirming the relationship on Instagram last Sunday, February 11 with a picture taken at Ellen DeGeneres' 60th birthday party.

Schumer's new film, I Feel Pretty, opens in Irish cinemas on May 4.
