Sauce Gardner is peeling back the curtain on his love life ... telling TMZ Sports things are pretty "cool" with Ice Spice -- and as it turns out, LeBron James had a role in their coupling!!
We caught up with the New York Jets star out in L.A. this week ... and asked him all about his budding romance with the rapper.
While Sauce didn't sing like a bird, he did say he liked how things were going .
