Junior Bradshaw, 33, and Kevin Liverpool, 36, were jailed in 2013 - two years after police uncovered a conspiracy to rob and behead the star and dispose of her body in a river.
The pair appeared at the Court of Appeal in London on Friday to challenge their sentences and they have now won their plea to have the jail terms reduced.
Bradshaw, who was sentenced to 18 years, will now serve 10, while Liverpool - who faced a life sentence with a minimum tariff of 10 years and eight months - must serve at least six-and-a-half years behind bars.
Bradshaw and Liverpool had plotted to snatch the singer from her English countryside home.
