Boyzone boy band member, Keith Duffy, accidentally flashed his bum on Saturday night's live Splash! semi-final.
The star's trunks fell down on more than one occasion during the latest live show, giving viewers quite the surprise when the camera panned to him underwater.
Duffy made light of his wardrobe malfunction, saying: "The trunks came off, what can I say? I'm just lucky I got them back on again in time Gabby, or I'd be standing here in my birthday suit."
