Just before unleashing Heartbreak on a Full Moon on Halloween, Chris Brown joins Casanova on the Fabolous-assisted “Left, Right.”

Casanova handles the raunchy first verse and chorus, before making way for Breezy. “She want me to pull my pants down,” he raps. “Wanna know what’s up / When I pull it out, you gon’ suck it or you trying to fuck?”

F-A-B-O pops up for the third verse with some of his patented punchlines and a reference to Slick Rick’s “La Di Da Di.” “She like to suck and put them hickies on your body,” he rhymes. “I like to fuck and put this dick inside her body.”

This is the latest collaboration between Fab and Breezy, who toured together earlier this year. Yesterday, the duo also performed “She Wildin” and “Flipmode” at TIDAL X: Chris Brown.

Recently, Casanova — who celebrates a birthday tomorrow — shared a behind-the-scenes look at the making of “Left, Right” on Instagram. “A year ago I didn’t even know what a producer really did in the studio,” he wrote. “And look at me know co-producing a record with a legend, [Scott Storch].”
