Christmas Mass was held in Saint Peter's Basilica at the Vatican.
The mass got off to a tense start after a woman jumped a barrier and tried to touch Pope Benedict but ended up knocking him over instead.
The pope was not hurt and continued his walk to the main altar.
This isn't the first time someone has tried to get too close to the pope.
It happened last year at the Christmas Eve midnight mass.
Someone jumped the barriers and ran toward the pope as he exited mass before being stopped by security.
