Hi! How do you translate "almost over night" referring to a person becoming famous? In the text I'm reading they say: "The story of Jean-Michel Basquiat who became, almost over night, one of the most famous artists in America. He started by writing the phony name SAMO on the walls all over Manhattan and soon ended up on the walls of the best galleries in NYC. His favorite sujects: black people like him. " Thanks for your help!
