His interest in fashion is undeniable--from the haute couture houses of Dior and Vuitton all the way to...the Gap?

A recent report suggests that Kanye West has quietly been interning at the New York City headquarters of Gap, Inc., which houses the brands for GAP, Banana Republic and Old Navy.

"He is learning the fashion business from the inside and trying to do it quietly," a source told Us Weekly.

They say West is devoted and that "he works all the time, and one Friday night recently he stayed until 12 a.m.!"

Gap is a classic Americana brand, currently headed by designer Patrick Robinson.
