Cheers to an Epic 27 Years!

Britney turned 27 on Tuesday and spent the day doing appearances to promote her new CD in NYC.  First, Brit performed "Circus" and "Womanizer" on Good Morning America where she was given an awesome birthday cake (it took 60 hours to make!).  Later, Britney taped an appearance for the Christmas Tree Lighting at Rockefeller Center which will air on December 3rd.
