Tuesday (Sept. 11) marks the 17th anniversary the 9/11 terrorist attacks -- the deadliest attack in the United States to date. Since the 2001 attacks, September 11 has become an annual day observance and reflection on the tragic events.
Many celebrities extended their condolences on Tuesday, and Lady Gaga took to Twitter to pay her respects as well. The New York native wrote to fans, "I will never forget that day as long as I live. It reminds me in moments like these, as I reflect, the importance kindness and love in this world."
The singer then suggested her followers honor the lives that were lost on that day and closed the tweet out with #NeverForget.
