Ellen DeGeneres, Serena Williams, John Stamos, Joan Rivers, Cheyenne Jackson, Don Lemon and Pauley Perrette tweeted on the tenth anniversary of 9/11.
Singer Sam Harris, who married his husband Danny Jacobsen in 2008, wrote on Facebook: "Thinking about 10 years ago. I was to take a flight, and make my official move, to LA from NY on Sept 11th, and changed my flight to the 10th as I had finished working on Liza's [Minnelli] segments of the Michael Jackson 30th Anniversary show. On this day, my phone rang and rang at the crack of dawn. It was Liza saying 'they're bombing NY' and I turned on the TV and watched the world change forever. Danny was stuck in Las Vegas. Wherever I live, NY is the home in my heart. Our hearts are heavy today."
Talk show host Ellen DeGeneres tweeted: "Ten years ago today, the world changed. I hope everyone finds time to remember those we lost... and to tell someone that you love them."
Actor Cheyenne Jackson remembered Mark Bingham, who died along with the 40 other passengers of United Airlines flight 93 when the plane crashed into a field near Shanksville, Pennsylvania. Bingham and several other passengers attempted to regain control of the plane. He came out gay to his mother at age 21.
"Thinking of u Mark Bingham, and everyone we lost," the recently married Jackson messaged.
Comic Joan Rivers wrote: "September 11 is a difficult day for us all. My thoughts are with the families of the many victims, and my hope is for a safer tomorrow."
Gay ally Pauley Perette echoed a similar sentiment, "Let there be peace on earth & let it begin with me."
"Love will always conquer hate," wrote John Stamos. CNN anchor Don Lemon was briefer, just one word: "Godspeed."
Serena Williams dedicated her U.S. Open match to the victims of 9-11 and their families: "My thoughts and prayers to all who lost loved ones on 9-11. I know the entire country is with you today. I'm playing for you today."
