Oliver Tree's bittersweet final social media posts before fatal helicopter crash revealed

Oliver Tree's final social media activity before the helicopter crash that claimed his life showed him enjoying a trip to Brazil.

The singer-songwriter has died at the age of 32 after a helicopter collision in the South American country as part of an aviation disaster that has resulted in six deaths.

Tree, full name Oliver Tree Nickell, was on board the helicopter with Lucas Vignale, Lucas Brito Chaves, and Gaspar Prim - an Argentinian YouTuber known as Gaspi, and pilots Alexandre Souza and Charles Marsillac also died in the crash when two helicopters collided in the air.

The musician, known for his bowl hair cut, had only recently posted footage of him enjoying his time in Brazil where he played football and palled around with fellow personality Iae Break.

One minute he's jumping around a football pitch holding aloft a replica of the World Cup, the next it's being announced that he's one of six who were killed in the horrific crash.

Tributes to Tree have come in from many corners, with KSI being among the many to speak out about the passing of the musician as he said he didn't want to believe the 'Miss You' artist was gone.

They'd worked together on the song 'Voices', and KSI said he desperately wished the whole thing was 'just one of his pranks'.

“Can’t believe I’m actually having to type this,” the influencer wrote.

“You’re 32 man. You should still be here. You still had so much life to live. So much music to make. So much content to make.

“You’re a legend and will always be a legend. Still doesn’t feel real. Genuinely feel sick. I love you bro.”

Tree had been on his World’s First World Tour where he planned to visit 30 countries and play 70 shows.

Before he died the musician had said what he wanted to be done with his wealth when he passed away, indicating he wasn't going to give it to anyone and had instead set up a foundation where a committee would vote on where to give the money from his estate.

"I don't believe that any of the wealth or the things that get made from it is mine," he said on the Zach Sang Show back in April.

"So when I die — I've set it up — my will is set up that when I pass, my family, no one's going to get a penny."

He went on explain: “The idea is, when I die, all the money is going to go back to the arts.

“So I’ve set up a foundation, it’s called Dr. Oliver Tree's Art Grants for Baby Geniuses and it’s set up so that basically the interest generated from my music, we’ll take mostly that, but there’s also room for other money, because when I die, my art will continue - and probably be worth more than it is now.

"People will finally appreciate my stupid f**king videos or my stupid f**king songs. That's when people appreciate you, when you're not there anymore."
