Fox News chief religion correspondent Lauren Green was invited to perform for Pope Benedict.

Green recounted the incredible experience today on Fox and Friends Weekend. She played piano during the concert in honor of the pope’s brother, who turned 90 years old, at the Vatican.

“Nervous doesn’t even explain the level of stress that was there on that day,” Green said, adding that she said many prayers before performing.
