The Wanted star Max George has vowed never to watch a killer whale show ever again after watching a new documentary about animal captivity.

The singer tweeted his thoughts after watching the "heartbreaking" flick Blackfish, which investigates killer whale shows at marine attractions such as SeaWorld.

The 'Glad You Came' man said: "Watching Blackfish, killer whales should not be kept in captivity. It's a disgrace. So upset and angry. I won't watch an orca show again."

He simply concluded: "Heartbreaking."

George meanwhile achieved a "life dream" last year after he indulged in some swimming with sharks whilst in Australia.
