10 Adrian tried to rescue Natalie Merry, 18, from a devastating fire in Ayr, Scotland, in January

Insane Championship Wrestling star McCallum was found dead at 11.30am on Wednesday in Ayr, Scotland, hours after sharing a haunting tweet.

His message - a direct quote from Ricky Gervais' hit Netflix comedy After Life - was posted on Twitter on Wednesday morning.

He wrote: "One day you will eat your last meal, you will smell your last flower, you will hug your friend for the last time.

"You might not know it's the last time, that's why you must do everything you love with passion."

Stunned pals of the ICW champ, from Ayr, said they were unaware he had any issues.

'I TRIED EVERYTHING'

British WWE ace Drew McIntyre led the tributes, saying: “Sleep well my brother. I’ll see you down the line.”

Wrestling legend Chris Jericho said of McCallum, a coach on BBC reality telly show Rogue to Wrestler: “I’m truly saddened. May God give you peace my friend.”

Cops said the death was not suspicious.

The brave pro grappler told in January how he “tried everything” to save tragic 18-year-old Natalie Merry from a fire.

We told how McCallum heard his trapped neighbour’s screams as the inferno tore through her home.

HAUNTING FINAL TWEET

He caught her boyfriend Alistair Innes, 22, as he leapt to safety from the first floor – then tried in vain to smash down the front door to get to Natalie.

At the time, he said: “As I ran to the house, the living room window exploded.

"A boy was hanging out the top window so I yelled at him to jump.

“I caught him as he came down and then I tried to break down the door. But the heat was too much.

"I could hear the poor girl screaming. I tried everything."

Student nurse Natalie was pronounced dead at the scene.

Breaks my heart. RIP my friend. You were always so wonderful to me and I’ll be forever grateful that I knew you. Give Trav a big hug from me Paige

Her distraught boyfriend posted a heartbreaking tribute on social media.

Alistair wrote: “I’m absolutely heartbroken, had the happiest and best 2 years of my life, she made me so happy, gonna miss waking up to her beautiful wee face everyday.

"Love you so much Natalie.”

Lionheart had been a top wrestler for the last 10 years.

He appeared on a host of popular shows including WWE and TNA and was one of the UK's most famous wrestlers.

Fellows wrestling stars paid tribute to the star.

WWE superstar Paige tweeted her tribute, and remembered another tragic British wrestler Kris Travis, who died of stomach cancer in 2016.
