He's the Hollywood action hero who has one of the most envied physiques in the industry.

But on Thursday, during an appearance on The Tonight Show Starring Jimmy Fallon, Chris Hemsworth 35, revealed that even the God of Thunder is prone to some emotional eating.

The hunky Australian star shared a hilarious behind the scenes video of 'fat' Thor singing the classic Nine Inch Nails tune, Hurt.

Avengers: Endgame premiered earlier this year, instantly becoming a box-office smash by grossing 2.7 billion worldwide, the second highest return for a film ever.

'Avengers: Endgame shattered all these records,' began Fallon, 'and everyone credits Fat Thor.'

By now, fans who have seen Avengers: Endgame would know that things get pretty dark for the Norse deity.

What's happened to Chris Hemsworth? Hollywood actor shared a video of a down and out 'fat Thor' singing Nine Inch Nails' sad song Hurt during an appearance on The Tonight Show Starring Jimmy Fallon, left. Thor normally sports a ripped physique, right

In the film, a usually svelte Thor gets depressed over the loss of his family, letting himself go and trading his six pack for a beer keg and succumbing to the joys of pizza.

As it turns out, during this period of filming, Chris turned to music to get himself in the mood for the part.

He told Fallon that he was in his trailer between takes when he decided to pick up his guitar, asking himself, 'What would Thor want to hear right now?'

Wait, can I do that? In his interview with Jimmy Fallon, Chris said he was unsure if the video would ever be shown due to the strict spoiler ban imposed by the films directors, The Russo Brothers

His character, of course, was really going through it, so he decided to choose 'the saddest song in the world,' he explained.

'And I'm a terrible singer and a terrible guitarist,' he added.

Chris's pick for Thor was Hurt by Nine Inch Nails, specifically the haunting rendition by Johnny Cash, who covered the song in 2002 a year before he died .

In the interview, Chris went on to reveal that he was unsure if the video would ever be shown due to the strict spoiler ban imposed by the films directors.

'I didn't know if I was ever going to show it,' Chris told Fallon. 'Because it was in the trailer, in between a few takes.'

Chris is currently promoting Men In Black: International, in which he stars alongside Tessa Thompson, who played Valkyrie in “Thor: Ragnarok.” Out June 14th.
