Lampkin, who is engaged to rapper Jim Jones, was picked up by Edgewater police around 2:30 a.m. and charged with aggravated assault and disorderly conduct.
Witnesses said the 42-year-old stylist got mad when the unnamed victim took her seat and accidentally bumped someone. The victim ended up in the hospital, requiring stitches above her eye.
Lampkin was released a few hours after she was arrested, when Jones came to bail her out.
