Gayle Newland, 26, from Cheshire, was sentenced to eight years behind bars last year, but wept today as she won her appeal.
Ms Newland appeared via videolink from prison to hear she would be released on bail before a retrial.
Lady Justice Hallett, sitting with Mr Justice King and Mr Justice Dove quashed the conviction as unsafe and allowed the appeal on the basis of the directions given to the jury by Judge Dutton.
Newland is said to have posed as a half-Filipino, half-Latino man called Kye Fortune in order to seduce her victim.
