Happy Belated Birthday!

How do you expect me to remember your birthday, when you never look any older?

I hope your birthday was all that you hoped for.

Wishing you a belated birthday.

I am sorry I missed your birthday, you have had so many I lost track.

I hope your birthday was as special as you are.

Happy Belated Early Birthday!

Sorry I forgot the most important day of the year... your Birthday!

2, 4, 6, 8, sorry that this birthday cheer is late!

This wish is late so that you can celebrate your birthday longer.

I'm so lucky to have such a great friend like you... who'd forgive me if I forgot his(/her) birthday. Happy Belated Birthday!

Best wishes for your birthday afterwards.
