Hollywood is using social media to pay their respects to the victims and first responders of the Sept. 11 terrorist attacks that killed nearly 3,000 people in 2001.
By early Monday morning, Twitter was filled with several trending hashtags -- #NeverForget, #September11th, #911remembrance, #Remembering911, #GodBlessAmerica and #TwinTowers -- paying tribute to the devastating attack that occurred 16 years ago.
"Forever in our hearts and minds. #NeverForget @NYPDnews @FDNY," Hugh Jackman tweeted.
