Machine Gun Kelly said the birth of his and former fianceé Megan Fox’s baby, who is due any day now, will be “bittersweet” following the death of one of his best friends.

While mourning the death of Australian snowboarder Luke “The Dingo” Trembath, the 34-year-old rapper took to Instagram on Friday to pay tribute to his “brother.”

“Crazy… I didn’t even cry this hard when my dad died. I’ve lost a lot of friends, but I’ve never lost a brother,” he wrote of Trembath, who died at the age of 38 on Feb. 28.

“We’ll never get another Dingo on this planet. A true rockstar without ever needing to make a song, the most loyal, loud, charismatic, funny, and annoying human I’ve ever had the honor of knowing.”

He continued, “I’ll miss your epic toasts, I’ll miss dapping you up and my hand hurting everytime because you had some odd amount of Australian strength goin on, I’ll miss your bellyflops, I’ll miss watching you walk through the door and lifting the energy of every pivotal event in my adult life, I’ll miss you pissing me off, but most of all I’ll miss your laugh. you were the glue between all of us.”

Kelly went on to reveal how hard it was telling his daughter, 15-year-old Casie, the news. She loved him “so much,” he said, so it was one of the “hardest phone calls.”

“I’ll never forget when she was too young to understand your name was Dingo so she called you Ping Pong,” he said.

“I feel like your up there with my new child, dressed up in a hilarious costume making them laugh, getting ready to send them down. I couldn’t ask for a more bittersweet birth blessing.”

He concluded his caption by writing, “Life will always be less without you, but legends never die. we’ll all miss you brother.”

Kelly’s post comes a week after Page Six exclusively reported that Fox is “leaning heavily” on her older sister, Kristi Fox, as she awaits the arrival of her fourth child — she already shares three children with ex-husband Brian Austin Green.

“Megan is leaning on her sister Kristi amid her split from Colson,” a source told Page Six, referring to the rocker’s birth name, Colson Baker.

Despite their recent split, our insider said the “Bloody Valentine” singer “has every intention” of being a present father in the child’s life.

“He and Megan have still been in communication,” the source shared.

“He loves Megan and wants nothing more than to be a family unit.”

Megan, 38, and MGK broke up in November 2024 — four years after first linking up. They publicly announced their spit just two weeks after they revealed they were expecting their first child together.
