Billionaire G.O.P. front-runner Donald Trump is no stranger to self-aggrandizement; one could say any man resting his head in a gold-dipped penthouse, repeatedly referring to himself as one of the smartest guys he knows, and blasting any slight criticism he hears, lives with a heightened sense of self-importance.

The Donald’s head might just explode, then, when he sees the May 1 cover story in Fortune magazine. According to the New York Post, the upcoming feature pins Trump’s net worth at $3.72 billion, a quarter of the $10 billion he has boasted. It’s even below *Forbes’*s previous estimate of $4.5 billion, a figure that caused Trump to fly off the handle. “All I can say is Forbes is a bankrupt magazine, doesn’t know what they’re talking about,” he said.

On the new magazine story, Trump reportedly told Fortune, “Fortune has no idea what my assets are or the value of these assets. Nor do they understand or know my cash flow or the many successful transactions that make up my cash flow. Fortune has totally lost its way.”

The magazine found its way into obtaining an eight-year-old photo showing Trump flashing his middle finger at a photographer, according to the Post. That’s not exactly an image that screams “presidential,” which happens to be the face Trump has been working so hard to project as he tries to pivot from a loose-lipped, insult-hurling primary candidate to one suited for a general election.

A Fortune spokesman told the Post, “We’ll let the story and photo speak for themselves.”
