She was sitting in the public gallery as she was addressed directly by the judge after he jailed Reid, who had refused to leave her cell at HMP Styal, for a minimum of 20 years.
A woman who beat and abused her lesbian lover over several years before murdering her in May last year was sentenced at Manchester crown court today to life in prison.
Ms Vaux died in Platt Bridge, Wigan on 22 May 2016, malnourished and severely injured following years of beatings by Reid, the court heard.
Reid was also convicted of grievous bodily harm to another previous partner, Samantha Newns.
Reid's mother, Gillian Reid, 57, was cleared of murder but found guilty of assault occasioning actual bodily harm to Ms Newns.
She was given a 12-month jail sentence suspended for 12 months.
If she returned without cash, she would not be allowed back in the house.
On the day of her death, Ms Vaux was spotted cowering beneath a vehicle, and told neighbours she "just needed to rest".
In the run up to her death Lyndsey had confided in a friend saying: 'I'll be honest with you.
'Her health and physical well being went rapidly downhill in the last months of her life.
The court was told that Lyndsey Vaux, 30, had fallen under Reid's control and had lost contact with her daughter five years earlier.
'She would also often be seen walking around the streets in the local area without shoes or appropriate clothing, sometimes in flip flops and T-shirt in pouring rain.
She told another: 'I do get on her nerves and she just snaps'.
At the time of her death, Lyndsey had 90 identifiable external injuries on her body - which Becky Reid preposterously put down to the victim's frequently falling over due to a thyroid problem and her refusal to take medication.
But despite offers of help and police being alerted by anxious friends and locals, Lyndsey would protect her violent girlfriend and falsely claim she had been in accident or been attacked by someone else and no action was taken against Reid.
On another occasion, Lyndsey was stood in front of her house and Becky Reid was stood in the doorway.
Reid regularly kicked, punched and stamped on her victim, leaving her "looking like the elephant man".
Speaking after the hearing, senior investigating officer Bob Tonge said Ms Vaux had suffered years of "horrific domestic abuse" in a "classic modern slavery case".
He also said some neighbours "knew about this abuse and did nothing", adding: "We all have a responsibility to stand up to this kind of crime".
"My thoughts are with Lyndsey's family at this hard time, and I hope this sentence goes some way to finding them justice".
