Meanwhile, in a lie detector test for the outlet, Channing was questioned over whether he perfected the "smize", or smiling with his eyes - a term coined by Tyra Banks - when he was working as a model in the early 2000s.
"I don't know if I perfected it, but I worked. I didn't have to wait tables," he continued, adding that Tyra remains the "queen" of the smize. "I don't think many people smize better than her, other than supermodels."
