A$AP is using his new song to call out one of his exes.

In his new song, the rapper takes a thinly-veiled shot at his opponent.

A$AP is referring to the attack on RiRi by Chris in 2009, when he punched her in the face and left her with a split lip.

Chris was sentenced to 5 years of community service and 5 years of parole after he was found guilty of assault on his girlfriend, and later admitted the incident made him feel like a monster and would haunt him for the rest of his life. A$AP isn't letting Chris live it down.

The music video for "D.M.B." just dropped Thursday, and there are also images of A$AP and Riri tying the knot.
