The most epic whale photobomb has gone viral

There's a guy called Will Posner who's been travelling the world for 18 months, and one of his travel pics is literally taking the world by storm.

It's a moment he'll never forget! While traversing the waters of Tonga, Will was surrounded by humpback whales.

Can you spot Damon in this EPIC photobomb pic? 

He jumped into the water to swim with the whales and as he snapped a selfie, a massive whale surfaced right behind him...

Talk about a whale photobomb!
