Adding fuel to the fire, 50 Cent once claimed he'd bought out an entire section at a Ja Rule concert in 2018 to make it look like empty.
Fiddy shared a post of the empty seats on his Instagram and hilariously, photoshopped himself into it.
He posted it with the comment: "What a show, I mean just f****** great.
"Do it again my kid went to the restroom.
"LOL #bellator #lecheminduroi."
In further Instagram posts he claimed he'd bought out 200 tickets for the concert.
He said: "Lol at $15 a pop you can't lose, I got 200 tickets for 3 bands.
Looking back on the stunt in 2019 on Watch What Happens Live, 50 Cent told host Andy Cohen: "I just happened to see [the tickets], they were right there for you to buy, and I was like, 'they was so cheap, I might as well just buy them'."
The beef between the rappers is said to have gone back to the 90s when Ja Rule was robbed at gun point at a store in Queens, New York, where both are from.
Fiddy wrote in his memoir From Pieces To Weight that Ja Rule later saw him in a club with the person who robbed him and was incensed.
This is a story Ja actually denies now, saying their bad blood stems from the days the Murder Inc. crew shunned 50 and during the shooting of a music video for his single 'Murda 4 Life'.
Since then the pair have had some pretty infamous altercations.
Their feud became real public knowledge when Fiddy called out the fellow rapper in some serious diss tracks.
'Back Down' was famously featured on the star's Diamond-selling 2003 debut album Get Rich or Die Tryin'.
So it seems when it come to celebrity beef Taylor Swift, Kanye West, Eminem and MGK may have done pretty well throwing shade.
However, none quite take the crown like 50 Cent and Ja Rule in the modern era.
