In the case of K. Michelle and Idris Elba, time doesn’t heal all wounds.

Michelle shaded Elba for the track “Confidential” in an slick move to tease a cut called "Post Delete" from her upcoming album.

“My favorite song on the album so far," she wrote in the deleted post. “Still singing about him. Smh. I realize sometimes nothin ain’t nothin’. F**k him and that baby momma, oh and his new song sucks, stick to what you do.”

Michelle and Elba used to date on the low, but reportedly ended it because he was in a relationship and later had a child with current girlfriend Naiyana Garth. The Memphis-born recording artist sang about the Idris drama on her last album, Anybody Wanna Buy a Heart? 

Is it time for her to let it go or does Elba deserve the shade?
