In the wake of the September 11th attacks, thousands of people took to social media to express their grief and solidarity. While most people remember where they were and what they were doing when they heard the news, there are some who used the tragedy as a springboard to express their feelings about a range of issues. These are the most insightful and thought-provoking tweets I’ve found on the subject, and they truly deserve to be seen and shared.

Musical mega-star, Justin Bieber, tweeted a range of songs about the 9/11 attacks, including “Never Let You Go,” “One Less Lonely Girl,” and “Baby.” One of his followers responded by asking for more songs about the tragedy, and Bieber obliged with “Let Me Love You,” “Believe,” and “Too Good to Be True.” His next album, Purpose, is named after this exchange.

All my love and prayers to the families. Sending lots of positive energy to America.” Bullock had just wrapped the third season of her TV series, The Astronaut’s Wife, when the attacks happened, so she might have been unaware of what was unfolding in real life.

As an aside, would be nice to meet some nice New Yorkers in a pub just off Hunger Street. There’s a real culture there that I want to absorb.” She most recently hosted a tv talk show, Exclusive, which covered topics such as Brexit and the European Union, and is now co-presenting and writing a new script for Good Morning England!
