The 18 year went viral on twitter after boastfully posting a video of her pouring boiling hot water on her 17 year old friend before stabbing her in the leg.

The victim is said to be fine now although at the time had ran outside into the street to get help, and was later treated at Kings College Hospital for non-life threatening stab wounds.
Princess will now be sentenced in a hearing on 9 May, until then she remains in police custody.
A senior CPS at the hearing said: “Owusu-Ansah has pleaded guilty to stabbing her former friend.
“She turned up at the victim’s home and put her in absolute fear for her life.
“While this was happening, she gratuitously recorded the events on her mobile phone and posted this on social media.
“I hope that with these early guilty pleas and a sentence date fixed, the victim feels that we are well on the way to justice being delivered.”
