Peso Pluma is a huge star in Mexico and a rising star in the United States.

But the 24-year-old's career may soon hit the most morbid of snags.

The CJNG Cartel, which is considered the most dangerous in Mexico, has threatened the singer's life.

In a banner posted above a bridge in Tijuana, the cartel wrote, "It will be your last performance for being disrespectful and having a tongue if you show up, and we will f*cking kill you."

It isn't uncommon for Mexican performers to be killed by the cartels.

Pluma's next show is at the Rosemont Theatre in Chicago -- where he should be relatively safe.

He returns to Mexico for a show in Tijuana on October 14.

Earlier this year, Pluma was beefing with Tekashi 6ix9ine.
