Christina Aguilera recently stopped by the Ellen show for a chat, and in true Ellen DeGeneres fashion, she could not make it just strictly an interview, a fun little game was involved.

Christina Aguilera was definitely in the hot seat recently when she appeared on Ellen and played the game "Heads Up" She had to sing part of a song from other famous pop stars, for Ellen to guess who it was. But, some of the artists were definitely harder than others for Christina to quickly remember one of their famous songs.
