It's not too late to vote for Robin Thicke's Lil Wayne-assisted single "Pretty Lil Heart" in our Pop-Off click-off. Nor is it too late--because it will never be too late--to recap his performance of the slow jam on Late Night with Jimmy Fallon. Your day will be more soulful for it.

Wayne doesn't show up, which should never be surprising if you've got any inkling of his schedule; it's just Thicke, his piano and his hair, and his band--no Roots this go-round; no verse by anyone. None of this really detracts from the performance, though--both Thicke and his hair get very much into it. (Seriously--watch for the flips. Once you've started, it's impossible not to.)
