LOS ANGELES, Sept 20 — Rapper Chris Brown is all set to release his new album “Royalty” next month and his new single “Zero” is now out online.

The upbeat and funky tune centres on a break-up and talks about an ex, who once dumped him but now hints she wants him back. Could he be hinting at old flame Rihanna?

“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 hundred per cent but all I got from you, zero, zero.”

 Scheduled to hit radio stations on October 13, “Zero” serves as the second single off “Royalty” which is named after the 26-year-old crooner’s daughter
