Rafiq, of Cheshire Road, Smethwick, paid two men £50 to attack her after she ended their relationship, Wolverhampton Crown Court heard.
Shannon Heaps, 23, and Steven Holmes, 25, were found guilty of plotting to attack Ms Horsman at her friend's house in Tividale, West Midlands.
They were jailed for 12 and 14 years respectively. Both laughed when they heard the sentence and Heaps punched the air.
Holmes threw the acid and Heaps, who was at the door, was the one who put Rafiq and Holmes in touch with each other, the court heard.
