Sorry, ladies ... Alvin Kamara's smooth vocals won't be hitting the radio waves anytime soon -- 'cause the Saints RB says he has NO plans to pursue an R&B career despite his dope voice!!
Of course, Kamara SLAYED R. Kelly's "12 Play" at karaoke after beating up the Bucs on Sunday ... which caused some to wonder -- could the NFL star have a future in music??
We asked the New Orleans superstar straight-up at the Sports Illustrated Sportsperson Of The Year ceremony in L.A. Tuesday night ... and, sadly, he says no.
