Aaron Carter was trolled yesterday after a video emerged of him training amid his bout with former NBA player Lamar Odom.
The former pop star was seen in a boxing ring with an opponent where he missed the first swing. He was then seen doing some break dancing, before begging fans to watch his fight which he dubbed: "David vs Goliath."
Many fans commented on the "Crazy Little Party Girl" singer's frail and slender appearance after the video was posted on The Shade Room.
"He could’ve kept this in the camera roll," one person wrote online.
"Just. Say. No. Kids," a second added.
"Lmao he about to take the biggest L," a third chimed in.
The former teen heartthrob and the Keeping Up With The Kardashians star have will fight in on June 11 at the Showboat Casino in Atlantic City.
At 6ft10in, 41-year-old father-of-two Odom is nine inches taller than "Crazy Little Party Girl" singer Carter. Odom is also eight years older than the former child star.
"It's gonna be a war, man," Celebrity Boxing boss Damon Feldman told TMZ Sports.
"It's gonna be a knockout, no doubt."
Odom inked his deal for the match on January 20, while Carter signed his contract on November 29. However he said he actually hoped to fight pop star Justin Bieber - who Carter claims he paved the way for.
Both Aaron and the two-time NBA champ have survived drug addictions, which they treated at rehabs in 2011/2017 and 2015, respectively.
Teen idol Carter filed for bankruptcy at age 24. He has been since been making a living by making X-rated videos on OnlyFans and CamSoda.
When the news initially broke that Odom and Carter were going to go head to head in a boxing bout - some fans hoped the fight wouldn't go ahead at all.
"Aaron Carter won't even pass the drugs test," one fan wrote online.
"Have the paramedics on standby for Aaron," a second shady comment read.
"This is a joke but really it's not cool at all Lamar has brain damage from a od! hope it doesn't go through," a third hoped.
"Shows you how having millions and going from Hero to Zero over Drugs can lead you do whatever you have to," a fourth person added.
"He's gonna kill that little boy with one punch," a Lamar fan declared.
