[Intro]
Yo yo… aaj ka din khaas se,
Meri baby ka birthday aaj se! 
Cake katte hi smile teri,
Dil bole — Tu Hi Meri jaan se! 

[Verse 1]
Aaj tere naam ki mehfil saja du,
Chaand taare tere kadmo mein laga du,
Tu hase toh dil mera khush ho jaave,
Tere liye saari duniya bhula du. 

[Hook]
Tu meri baby, ghani pyari se,
Tere te hi duniya saari se,
Janamdin pe bolun ek baat,
Tu mere dil ki rani se! 

[Chorus]
Happy Birthday Baby,
Aaj tera din se baby! 
Nach le, gaa le, full enjoy kar,
Aaj party teri se baby!

Happy Birthday Baby,
Tu lage sabte crazy! 
Meri jaan, meri queen,
Tu hi toh hai meri baby! 

[Verse 2]
Teri aankhya mein kajal kaali,
Teri smile lage sabte nirali,
Jab tu bole “oye sun na”,
Dil ki dhadkan ho jaave double wali! 

Tere sang har pal special lage,
Tere bina sab kuch empty lage,
Bas yunhi rehna mere paas,
Tera saath hi sabte best lage. 

[Rap]
Desi chhora dil te bole,
Baby tu manne ghani pasand,
Tere birthday pe kasam se,
Tanne rakhunga dil mein band! 

Na koi tension, na koi load,
Aaj bajega birthday mode,
Cake kaato, photo khincho,
Baby aaj full party road! 

[Final Chorus]
Happy Birthday Baby,
Meri jaan tu sabte crazy! 
Khush reh tu har pal,
Bas itni si wish hai meri!

Happy Birthday Baby,
Tu meri life ki melody,
Aaj bhi, kal bhi, har janam,
Tu hi rahe baby!
