Rihanna Home Shooting

Rihanna was home with her 3 kids at the time an assailant targeted their L.A.-area mansion with gunfire -- A$AP Rocky, the father of the kids, was also home.

Sources with direct knowledge tell us ... the singer was shacked up inside her house with the children she shares with A$AP -- namely RZA, Riot Rose, and Rocki Irish -- before all hell broke loose on Sunday afternoon.

The suspected shooter, Ivanna Lisette Ortiz, allegedly fired off several shots from her vehicle at the residence ... but luckily RiRi and her youngsters were not injured, our sources said.

Ivanna Lisette Ortiz -- the 35-year-old woman accused of shooting at Rihanna's home on Sunday -- apparently posted a bizarre message addressing the singer just weeks before the incident.

A February 23 Facebook post from Ortiz's account reads ... "@badgalriri Are you there? Cause I was waiting for your AIDS 5-head self to say something to me directly instead of sneaking around like you talking to me where I'm not at."

In another post, Ortiz allegedly shared an eerie video mentioning Cardi B.

Authorities have released the name of the female suspect accused of firing gunshots into Rihanna's home on Sunday.

According to law enforcement sources, the suspect has been identified as 35-year-old Ivanna Lisette Ortiz.

Ortiz was booked for attempted murder, with bail set at $10,225,000. She remains in custody.

A woman was taken into custody Sunday afternoon after firing multiple rounds from her vehicle toward Rihanna's house ... TMZ has learned.

Law enforcement sources tell us the suspect -- described as a female around 30 years old -- drove up near the Los Angeles property and discharged several shots in the direction of the home. It's unclear what prompted the incident.

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.
