Taylor Swift: 21st Birthday at the Recording Studio!

Taylor Swift heads to a recording studio on her birthday, Monday (December 13), in Nashville, Tennessee.

The country star turned 21! Happy b-day, Taylor!!!

On Sunday, Taylor celebrated early with party hats and a pizza decorated with 21 candles that two of her bandmates brought over to her place.

“I don’t feel older all of a sudden. It’s a state of mind thing, how you see the world, being excitable, staying excitable and impressionable and doing your best not to become jaded or bitter,” she told Nashville radio station WSIX.
