Sadly today is not a nationally recognized holiday but it should be because today is Britney Spears’ birthday!

The “Womanizer” singer turns 29-years-old today and hope she has an amazing day. Not too amazing though, we don’t want to be reading and writing about it tomorrow.

The last couple of days have been pretty tough for Britney and her family and hope she just keeps her head up and enjoys those that her close to her.

Happy Birthday B!
