Kangana had her birthday party, and she was sad.  I can only speculate why she was so sad, so let me speculate.

1. No one came to her party, except awkwardly dressed people.

2. No one gave her presents.

3. No one saw Kangana her naked.

4. Kangana forgot to flash her panties for the camera.

5.  She forgot to spray tan her legs, again.
