Christina Aguilera will enjoy a big, belated birthday party on New Year's Eve.
The star was actually 30 on December 18th but was too busy promoting her movie Burlesque
Now Christina plans to make up for it, by having a huge party which will also ring in 2011.
"I’m a Sagittarius. But, because I was working so much on the movie, I postponed my birthday party, so New Year’s Eve is my big 30th birthday party."
