The GRAMMY winner is set to perform a ballad in Spanish, called "Mas Alla," before Pope Francis' mass at Madison Square Garden on Friday night. Estefan performed the same song for Pope John Paul II in 1995.
"Nervous? Of course!" Estefan confessed. "If you don't get nervous before getting up in front of a lot of people much more so when the Pope is involved then something is wrong with you. You're not human or something."
On Thursday morning, Moby joined forces with Jamaican dancehall rapper Sean Paul, performing a concert for environmental change on the National Mall.
"I want to do my part and talk from my heart," Sean Paul told ET.
One downside to the Pope's visit was the traffic jams, but Jackman told us he's hardly affected since he rides his bike a lot of the time.

"I know it sort of annoys people but I think it's worth it," Jackman said. "I think he's an amazing man."
