Max George wants his former The Wanted bandmate, Tom Parker, to know he has his back.

Showing his support on social media, George shared a photo compilation of Parker and the band on Instagram.

He dedicated a touching message to Parker, writing: “First of all.. I think the bravery of Tom and Kelsey announcing their situation is incredible. It’s obviously a devastating and scary time… but for those who don’t know Tom I will say this. There is nothing that he has ever given up on and has never taken no for an answer.”

First of all.. I think the bravery of Tom and Kelsey announcing their situation is incredible. It’s obviously a devastating and scary time… but for those who don’t know Tom I will say this. There is nothing that he has ever given up on and has never taken no for an answer. His heart is the size of a lions, and it is his drive and passion that has always led The Wanted and made sure we are looked after the right way. Speaking as a brother, a friend and a band mate.. I know that you will conquer this as you have every other challenge you have ever faced. We are all on this journey together… and I can’t wait to get back on the stage with you and the boys and have a proper celebration when you’re better. You got this my man. I love you, Kels and all the family with all my heart and I’ll be right here.❤️

Explaining that he is “undergoing treatment,” the 32-year-old added, “We decided, after a lot of thought, that rather than hiding away and trying to keep it a secret, we would do one interview where we could lay out all the details and let everyone know the facts in our own way.”

Hey guys, you know that we’ve both been quiet on social media for a few weeks and it’s time to tell you why. There’s no easy way to say this but I’ve sadly been diagnosed with a Brain Tumour and I’m already undergoing treatment. We decided, after a lot of thought, that rather than hiding away and trying to keep it a secret, we would do one interview where we could lay out all the details and let everyone know the facts in our own way. We are all absolutely devastated but we are gonna fight this all the way. We don’t want your sadness, we just want love and positivity and together we will raise awareness of this terrible disease and look for all available treatment options. It’s gonna be a tough battle but with everyone’s love and support we are going to beat this. Tom and Kelsey xxx @ok_mag

In an interview with OK! Magazine, Parker said he was diagnosed with stage 4 glioblastoma six weeks ago.

“I knew something wasn’t right, but I never expected it to be this,” he said.

Despite the diagnosis being terminal, Parker said, “I’m going to be here. I’m going to fight this.”

The diagnosis came after the singer suffered multiple seizures in July.

Parker is married to actress Kelsey Hardwick, with whom he has a 16-month-old child, Aurelia, and are expecting their second baby.
