Rihanna, Kim Kardashian Step In For Teenager Jailed For Life For Shooting Dead her Abuser 

Kim K, Rihanna and Cara Delevingne are demanding justice for a woman who has spent the last 13 years in jail for killing a man who held her captive as a sex slave when she was just 16 years old.

Cyntoia Brown was sex trafficked by a pimp named Kutthroat who was physically, sexually and verbally abusive and eventually sold her to 43-year-old Nashville realtor Johnny Allen, a court heard during her trial in 2004.

Brown, who feared that former Army sharp shooter Allen planned to kill her, eventually grabbed one of her captor's guns and killed him, Fox 17 reports. 

But when the case came to court, she was sentenced to life in prison. She won't be eligible for parole for at least 51 years.
