The Wanted's Tom Parker made a surprise appearance at the band's show in Bournemouth on Monday evening after undergoing cancer treatment in Spain.
Tom, 33, was diagnosed with glioblastoma and recently returned back to the UK following almost a month's worth of treatment at a specialist clinic.
Fans were over the moon earlier this week when he turned up for the third concert of the Wanted Reunion UK tour.
Sadly Tom had to miss the previous shows in Glasgow and Newcastle.
Right before the end of their show, the boys - including Max George, Nathan Sykes, Siva Kaneswaran, and Jay McGuinness - welcomed Tom, who emerged sitting on a throne.
Nathan told the crowd: "Give it up for Tom Parker!"
"As you guys can probably tell there is a massive space in this band tonight. And we love Tom as much as you do.
"In fact, we’ll be big-headed and say that we love him slightly more, which is a lot. We can’t wait to have him back which will be very soon. He sees all your messages and everything."
The Wanted also shared a snap of their reunion on Twitter. It showed the boys all on stage as they ended the show.
"Like the king that he is! The f**king legend that is @TomParker [heart emojis] Bournemouth, that was so special!!!!" they said.
Tom also shared the snap to his Instagram page, calling the stage his 'happy place'.
Before being unable to attend the first two gigs, Tom explained to fans what was happening.

"So, as most of you know, I’ve been out in Spain on a treatment programme for the past couple of weeks," he began in the caption.
"It was only meant to last 20 days but due to a couple of logistical changes with tests and results it won’t be complete until the end of the week now which has delayed our journey home."
He continued: "I’m obviously gutted that I’ll be missing the first few shows but as I’m sure you will understand, I have to complete my treatment cycle.
"I’ve been zooming into rehearsals all week and I know that the show will be incredible and that my boys will hold the fort until I’m back."
The Glad You Came singer hopefully signed off: "Can’t wait to see you all very soon, hope you all enjoy the show. Much love. Tom x."
