50 Cent is set to debut his new single “My Life” featuring Eminem and Adam Levine live on NBC‘s show The Voice tomorrow night, with an official video which was shot in Detroit to be released shortly after, but for those who can’t wait until then, Myspace put out a thirty second preview six days ago (that went unnoticed until now) of the new track which features the business minded rapper we all know and love rhyming over a beat by S1, who is famous for the work he did on Kanye West‘s track “Power.”

In the short preview, 50 Cent also sends jabs toward former G-Unit members The Game and Young Buck, who he says he tried to help but they both stabbed him in the back.

The Game is currently on the verge of releasing his new album Jesus Piece and his new television show “Marrying The Game” recently debuted, while Young Buck is currently behind bars for weapon charges.
