50 Cent trolled Irv Gotti‘s death on Instagram, writing “LOL” as he was pictured next to a tombstone emblazoned with the phrase “RIP.”

The rapper jumped on IG after news broke Wednesday that Irv had died … 50 posted the photo of himself sitting next to the “RIP” scrawled tombstone and exhaling smoke from a hookah.

In the caption, Fitty wrote, “I’m smoking on dat Gotti pack,” but then softened his language with “nah God bless him LOL,” alongside an image of Irv — the co-founder of Murder Inc. Records.

Obviously, there was no love lost between the two music moguls who had a longstanding beef dating back to 1999, when Fitty’s friend was supposedly robbed by Ja Rule — one of Murder Inc.’s most famous rappers. Irv also produced albums for other major artists … including Jay-Z, Ashanti, DMX and J Lo.

At the time, Fitty’s career was just taking off and he didn’t get along with Irv and Ja from the get-go … there were several clashes — one occurred in 2000 when Ja and 50 got into a fight at an Atlanta nightclub. 50 and Irv never hugged it out before Irv’s passing.

As we reported … Irv died Wednesday at 54 in New York City … but his cause of death is still unknown, although he had recently been battling health problems. Last year, Irv suffered a stroke and was forced to walk with a cane. He also struggled with diabetes and tried to change his poor diet per his doctor’s orders.

By the way, Irv’s record label was the subject of a five-part 2022 BET documentary, “The Murder Inc Story.”
