The 18-year-old American Idol winner has made a vow of chastity and even wears a purity ring to show her dedication to her Christian beliefs, reports Starpulse.com.
The star declared, "I don’t want to give away bits of my soul to lots of different guys – I want to give all of myself to the right man on the right night, and the right night is my wedding."
Sparks is not the only celebrity to make a vow of chastity. The Jonas Brothers and singer Miley Cyrus also wear rings to remind themselves of their commitment to preserving their virginity.
