Hugh Jackman has revealed that some of his friends refer to him as 'Guppy' because he sleeps 'like a guppy out of water'.

Jackman explained to ITV's Good Morning Britain, "I am nicknamed Guppy because of the way I sleep, like a guppy out of water, if you've ever seen a fish out of water they flop around.

"If you ever see me on a plane or sleeping in a hallway or wherever then I'm literally jumping around like a guppy out of water. It's sort of embarrassing and it's been slightly dangerous for my wife at times, she's had to duck if I'm dreaming. The way I sleep is not normal."
