Ten years ago the world changed when nearly 3,000 people were killed in the terrorist attacks at the World Trade Center in New York City and the Pentagon in Virginia on September 11, 2001. Celebrities took to Twitter to reflect on the anniversary of that tragic day and honor the victims and heroes.
