Romelia Florentina Radu, 32, and Petre Niculescu, 39, were each sentenced to 14 years in prison over a catalogue of horrific abuses involving the child and eight other women.
The young girl who was found by police in a hotel was forced into street prostitution and made to have sex with up to 15 men per day during her horrific ordeal in Paddington, west London.
Radu and Niculescu, who started operating in the capital in 2013, physically and verbally abused the 14year old threatening to harm her family at home or to burn down her room if she refused.
The girl, who is now 15, said in a statement: 'They would slap me, push me and grab my hair. Many times I was left with bruises and marks on my body.'
She was among nine victims lured to the UK by the couple with the promise of work in shops and restaurants - only to face a life of prostitution and abuse.
The young girl was forced to change into 'sexy' clothes and put on makeup because she 'had the face of a child' when she arrived in the UK in 2016 after being lured from a poor family, Kingston Crown Court in Surrey heard.
Jurors were told that the girl - who was told not to reveal her true age to anyone was then forced to have sex with men every day for four months.
She said: 'Many times it was painful and I was disgusted.'
