Rap song with Jamaican hook?

I'm not sure if it's a new song or and older song, I only caught the end of it on the radio the other night. There's a girl rapper that does a verse before a Jamaican guy comes in with the hook. I'm not too sure as far as lyrics go, but he repeats it over and over as the music fades out. I was trying to guess, and the girl rapper had sort of a Lil Kim sound while the Jamaican guy sorta sounded like Shaggy - I searched and found nothing with either artist. Any idea what song this could be, because I'm at a complete loss.
