Amy Schumer crashed a wedding in Ireland on Friday (14.08.15).

The 'Trainwreck' actress and director Judd Apatow -- who were in Dublin to promote the new movie -- gave the bride and groom an unexpected surprise when they turned up at a local pub.

Judd had arranged to meet local singer Glen Hansard for a drink at the bar, where it just so happened a wedding party was underway.

The trio gave guests an impromptu sing-a-long to the tune of Irish song 'The Auld Triangle'.

Guest Steve Cummins, who pictured Amy, Judd and Glen with the bride and groom, tweeted: ''Who shows up for @jpswaine and Eithne's wedding only @amyschumer Glen Hansard and Judd Apatow (sic)''

Amy recently revealed she thought she was ''going to die'' while jet-skiing with new pal Jennifer Lawrence.

She recalled: ''I drove first, so I was like, hang on! I drive like a mom who rented a convertible, you know, and I'm like, 'Woo!' and then she goes, 'Oh, can I drive before we go back?' and I'm like, 'Sure'. She just 'Hunger Games' flew! She grew up doing it so she's doing doughnuts, using her own wake. So I was screaming and I was sure I was going to die. I was like, well, at least I know how I'm going to die, and it'll say, 'Jennifer Lawrence and one other died today' and that's fine.''
