The show took place in New York last month.
"He had his agent fire all 30 of his staff after the fashion show and got rid of his phone so people can only contact him via email," an insider told the New York Post's Page Six.
"He had a nervous breakdown after the show, and that's what triggered it all."
The fashion show turned into a nightmare after a very late start. Because of the nearly-two-hour delay, some models passed out due to the heat while some others looked exhausted.
Probably thinking the entire thing was too painful to watch, some fashion editors apparently in attendance chose to leave the presentation early.
