Watch: Why is Hugh Jackman grabbing his balls?

Hugh Jackman has been getting a little handsy with himself. But it's not what you might think…

The Aussie actor was literally "feeling nuts" as he took one for the team in a mission to raise awareness for testicular cancer.

Watch the mesmerising video above, where he jumps in slow-motion, hands firmly clasped around his junk.

And yep… he's still a mega babe.

Is #feelingnuts about to become the new #icebucketchallenge?

We're not really sure what is actually "challenging" about this… perhaps the embarrassment factor of publicly posting a ball-grabbing video is a dare in itself?

Having been nominated by Sam Branson (son of Virgin CEO Richard Branson), 45-year-old Hugh, who has had a cancer scare in the past, went on to nominate a few other celeb pals like comedian Ricky Gervais, actor Neil Patrick Harris and former NFL player Michael Strahan.

Stay tuned for more ball-grabbing celebs. We can't wait.
