Trina and K. Michelle reunite.

Four years after “No More,” the hip-hop and R&B duo links up once again on their latest collaboration, “If It Ain’t Me.” Bashing a man who’s done her wrong, Trina kicks things off with a nod to Lil’ Kim’s “Queen Bitch” classic.

“Who you lovin’ when I go out on the tour?” she asks. “Bring back a check, I bet that bitch is such a bore / Who you lovin’, who you wanna be fuckin’? / I got ni**a-groupies at me, but my vibrator buzzin’.”

Meanwhile, K. Michelle has no time for her ex. “No more love, I’m wasted,” she sings. “Jack Daniels my baby / Pour it in my cup, forgot about you already / Ain’t no coming back to this / I just packed up my shit / Petty ni**as is the worst / I ain’t got time to be hurt.”

A Michael Garcia-directed video for “If It Ain’t Me” is set to follow. Based on the preview that Trina shared on Instagram, the clip will feature Dave East as the love interest.

Trina spoke with Rap-Up about “If It Ain’t Me” back in February. “Working with K. Michelle is easy,” she said. “There’s a great chemistry with me and her so that was one thing that made it even more of a blessing for her to be on the record.”

“If It Ain’t Me” is a single off Trina’s forthcoming yet-to-be-titled LP, which is set to be executive produced by Rico Love. The project will feature appearances by 2 Chainz, Boosie Badazz, Plies, Kelly Price, and her ex Lil Wayne.
