So far I can remember about 8 contestants who turned into lovers during a contest:
Couple: 1
Harsheet + Arshpreet - SVOI 1
Like: A UP Munda (Pappu Can't Dance Sala) + A Lovely Punjabi Sonee Kuri
Result: Already broken
Couple: 2
Chang + Deepali - Indian Idol 3
Like: Jackie Chan + Mallika Sherawat
Result: Lets see how far the relation continue
Couple: 3
Rahul + Vineet - JJWS (The most shocking couple 😆 Heeeheeeeheeee)
Like: Heath Ledger + Jake Gyllenhaal (From the movie Brokeback Mountain)
Result: Definitely made for each other. To me: "Kuch to sharam kaar".
Couple: 4
Mohit + Tulika - Indian Idol 4
Like: Two clowns in a circus.
Result: Syberia (-50 Degree)
Please add if there is any more.
