Shaq's hilarious response to Beale pic with Prince William

A photo of Kurtley Beale posing with Prince William in just his undies has gone viral, and even NBA legend Shaquille O'Neal has noticed it.

Beale posted one of the snaps of the year following the Wallabies' win over Wales in Cardiff on Sunday.

Rocking around in the sheds post-match in a pair of budgie smugglers and cradling a well-earned cold one, the Wallabies fullback was paid a visit by the prince, who'd been watching the match in the stands.

The pair posed for an incredible photo, with the suit-wearing William flanked by the half-naked Beale.

Beale added the caption: “When you rock up to the party feeling a little over dressed.”

The photo had close to 10,000 likes in just a few hours.

The Prince, a well known rugby tragic, looked to take it all in his stride and actually took a few photos with other members of the team.

And in a bizarre turn of events, Shaq has re-posted the photo on his own Instagram page, photoshopping his head onto Beale's body.

Yes, you read that correctly.

"It was a pleasure meeting you prince William," Shaq wrote.

Perhaps the big man is a bit envious of Beale's ripped rig?
