Chris Brown's new single 'Zero' leaks online

Rapper Chris Brown's new single 'Zero' from his album Royalty has arrived online.

On the upbeat and funky break-up tune, Brown talks about an ex, who once dumped him but now hints she wants him back.

"Now you're missing what we used to have/ Guess the vodka brought the feeling back," he sings before telling her in the chorus, "Ask how many nights I've been thinking of you, zero, zero/ Gave a 100% but all I got from you, zero, zero."

Scheduled to hit radio stations on October 13, 'Zero' serves as the second single off Royalty, following up lead cut 'Liquor'.

Titled after the 26-year-old crooner's daughter, the album is due out this fall.
