According to a confidential informant, who begged to remain anonymous, rapper Da Brat, real name Shawntae Harris, is back home after serving 3 years in prison for assaulting a cocktail waitress with a liquor bottle at Jermaine Dupri’s now defunct Studio 72 in Decatur.

Brat, who spent most of last year out on work detail, wasn’t welcomed home with lavish champagne-soaked parties and strippers. Instead, she is on house arrest and is required to notify her parole officer (whom she’s scheduled to meet with today) whenever she has to leave her home for doctor’s appointments or emergencies.

At 36, Da Brat finds herself washed up and alone for the first time in her life. According to my source, most of Brat’s industry friends have abandoned her — except for her “sister” LisaRaye, who calls her regularly to keep her spirits up. “No one else will return her calls,” said my source, who promised to deliver a message to Shawntae asking her to call me.

“No one but LR reached out to her while she was in jail,” said my source, who added that few people made the 2-hour drive from Atlanta to visit Da Brat “including JD.”

According to my source, Brat spends her days writing songs and working in her home studio. But without a record deal or a publishing deal, Da Brat has to rely on residual royalties from her distant hit records to pay her bills.
