Kristen Stewart was on hand to introduce the legendary Bon Jovi, who gave a rockin' performance for a great cause.
The lovely Blake Lively was also in the building to pay tribute to all those that lost their homes in the horrible storm. The "Gossip Girl" beauty also introduced music legend Billy Joel, who performed his hits including "Only the Good Die Young" and "Piano Man."
