Teyana Taylor: How'd I Get My Bikini Body? ... Popeye's.

Want that killer Teyana Taylor bikini body? Here's what you gotta do ... hit Popeyes and ignore the gym.

That was Teyana's plan after poppin' out a kid just 7 months ago ... and the results? MIND-BLOWINGLY AWESOME!!

Seriously, Iman Shumpert's lady spelled the whole thing out for us ... and yeah, it just ain't fair.

Only one question remains -- spicy or mild?
