Remorseless was caught on camera showing her true colours - in a furious rage in the minutes after stabbing her partner to death.
Body worn footage from police officers at the scene of the crime captured Lee's venomous fury as Paul Taylor lay dead or dying on the floor.
Despite what she had just done, Lee's anger showed no sign of abating as she ranted at police and neighbours, repeatedly swearing and issuing threats.
The footage was played during Lee's trial and gave an insight into her true frame of mind on the night she stabbed Mr Taylor to death.
Jurors were told how Lee had a history of carrying out domestic violence on Mr Taylor and other ex partners.
During a drunken row at her flat in Jarrow, in March, she was heard by a neighbour repeatedly threatening to kill her partner before finally knifing him in the heart.
The 44-year-old called 999 to summon help and gave a lying account that Mr Taylor, 45, had stabbed himself to death.
Jurors at Newcastle Crown Court rejected that account, clearing her of murder but convicting her of manslaughter. She will be sentenced next week.
