Are there any crossover events between gta v story mode and gta online?

There is no verified information indicating any crossover events between Grand Theft Auto V's story mode and GTA Online. The evidence provided discusses Donkey Kong Bananza, a Nintendo Switch 2 game unrelated to the GTA franchise. Without verified sources confirming such crossovers, I cannot state that any exist. Rockstar Games has occasionally added story mode characters to GTA Online through DLC, but specific crossover events as described are not confirmed in the available evidence. Any claims about such events would require verification from official Rockstar sources or reputable gaming news outlets.
