50 Cent, what took you so long? Almost five days have gone since Rick Ross came out with "Mafia Music," which talks about Fif and the mother of his child.

"I love to pay ya bills, can't wait to pay ya rent/ Curtis Jackson baby mama, I ain't looking for a cent/ Burn the house down," the husky Miami MC rapped on the record, referring to the last year's "suspicious" fire at a home owned by 50 (in which his son and ex-girlfriend lived). "You gotta buy another/ Don't forget the gas can, jealous, stupid mutha----er."

Thursday night, Hot 97 radio personality Miss Info debuted portions of 50's new song "Officer Ricky (Go Ahead and Try Me)" during one of her hourly news segments. Later in the night, he released the entire record to the Net. On the track he goes after Ross and DJ Khaled, and he once again calls out Lil Wayne.

"The cop f--- with Fox," 50 asserts, alluding to Ross' alleged prison-guard past and the rumors of a marriage between him and Foxy Brown. 50 later calls Brown a "bimbo."

"Must've thought he knocked me out like Kimbo," the G-Unit General adds. "Officer Ricky radio for backup/ See your a-- anyway, you know I'm gonna act up/ You wanna play with me when I don't wanna play?/ Have my n---as whip the skin off your a-- in broad day/ Screaming, 'Boss,' n---a , you ain't a boss/ Pu--- n---a, you're lost/ Listen, Officer Ross."

As the record comes to a close, in classic 50 fashion, the Queens-bred icon talks over the beat, saying that if Wayne wants to battle Eminem, he has to come through him first.

"This n---a is an appetizer," 50 says of his new beef with Rick Ross. "Where you at, Wayne? You're the full course meal, Wayne. You awfully quiet."

50 Cent's Before I Self Destruct was slated to come out in early February. It has since been pushed back, and no new release date has been announced. Besides "Mafia Music," Rick Ross also released his single "I'm the Magnificent," which features John Legend. Ross' new album Deeper Than Rap should be out sometime this spring.
