Kya hua kya nahin
Mujhko ye nahin pata
Kya hua kya nahin
Mujhko ye nahin pata
Meri koi kahta nahin
Aur kuch nasha nahin
I am in love
I am in love


Kya hua kya nahin
Mujhko ye nahin pata
Meri koi kahta nahin
Aur kuch nasha nahin
I am in love
I am in love


Ek to neend nahin aati
Nand ager aa jati hain
Sapno mein bhi chain kaha
Teri yaad satati hain
Aa teri yaad satati hain
Sach kahte hain log
Pyar hain dil ka rog
Arey sach kahte hai log
Pyar hain dil ka rog
Rog ye bura nahin
Dard ye bemaja nahin
Rog ye bura nahin
Dard ye bemaja nahin
Meri koi kahta nahin
Or kuch nasha nahin
I am in love
I am in love


Kya hua kya nahin
Mujhko ye nahin pata
Meri koi kahta nahin
Aur kuch nasha nahin
I am in love
I am in love


Oo oo oo
Mast baharo ka mosam
Aata yu kho jata pyar
Jo hum na karte to
Jeena mushkil ho jata
Jeena mushkil ho jata
Pyar nahin aasan
Juad gaya nata
Pyar nahin aasan
Juad gaya nata
La la lala


Maine jo suna nahin
Tumne vo kaha nahin
Maine jo suna nahin
Tumne vo kaha nahin
Meri koi kahta nahin
Aur kuch nasha nahin
I am in love
I am in love


Kya hua kya nahin
Mujhko ye nahin pata
Meri koi kahta nahin
Aur kuch nasha nahin
I am in love
I am in love
I am in love.
