The rap boss was wounded in the leg after the incident at a MTV Video Music Awards after-party.
Stone and her boyfriend BEAU DOZIER were inches away from Knight just moments before he was shot.
The 18-year-old tells the New York Daily News, "I left a few minutes before it happened.
"I was with my boyfriend and I told him, 'I've got to get out of here now. I have a bad feeling.'"
