Nick Cannon's Turban Not a Sticking Point for Late Night Show on FOX

Nick Cannon's getting a warm welcome at FOX for his new late night TV show, and so is his turban ... TMZ has learned.

Sources close to the situation tell TMZ ... Nick will rock his signature headgear without concern or pushback from the network. That wasn't the case in the latter part of his nearly 10-year run as host of "America's Got Talent" on NBC.

Sources said the Peacock Network wasn't jibing with his look on 'AGT,' and unleashed its wrath on him over a "black card" joke he made during a Showtime comedy special.

That dispute led to Nick quitting 'AGT', and leaving millions on the table.

As for his new FOX gig, we're told it has to be a weekly show, because Nick is currently finishing up his master's degree at Howard University. When he's done, it'll free him up to do a nightly show. We're told the show's set to debut in early 2019.
