Our law enforcement sources tell us the singer was home at the time of the shooting but is okay. It's unclear whether A$AP Rocky and their children -- RZA, Riot Rose and Rocki -- were at the home at the time.

Cops quickly rushed to the scene and took the woman into custody without further incident. Authorities are now investigating the motive.
