John Barrowman's parents are excited as anyone to watch their son and the former Doctor Who star eat bugs on I'm A Celebrity... Get Me Out Of Here! 2018.

They're flying out to Australia to support him, and even sent him a cute good luck video on Twitter to prove it.

The actor was a surprise addition to the list of jungle-bound celebs when it was announced on Tuesday, and he's already in Australia ready to link up with his co-stars ahead of the show's launch on Sunday evening.

His parents, Marion and John Sr, are heading out to support him – and they took the time to film a quick message for him before their flight.

"Were really excited about John going into the jungle in Australia," John Sr says in the clip. "And, it's going to be a great time for us because we're flying out there to be a big part of the party, and to celebrate the winner who comes out of the jungle intact..."

Turning to his wife, he adds: "Marion, we hope it's him, don't we?"

Check the clip out below.

Barrowman will be joined in the jungle by former X Factor star Fleur East, football manager Harry Redknapp, The Vamps guitarist James McVey and DIY: SOS host Nick Knowles, among others.
