Lady Gaga paid tribute to the victims of the Last Vegas massacre, which is now the largest mass shooting in U.S. history, by hosting a live meditation session. The Joanne superstar encouraged fans to join her for a live-streamed 20 minutes of silent meditation or prayer to calm inflammation and "connect us all through inner peace."

"My intention is to provide a forum for us all connect to around the world, as a calling for world peace and inner peace," she said. "If you choose to meditate with me I will explain how meditation is important in my life and how I will be doing I practice it before we get started. It will be very helpful to be in a quiet dark space, but anywhere is fine as long as we're together."

Gaga, however, did not stop at inner peace. The singer  urged U.S. leaders to act quickly to tighten gun laws. She tweeted: "This is terrorism plain and simple. Terror bares no race, gender or religion. Democrats and Republicans please unite now. Prayers are important but Paul Ryan, Donald Trump, blood is on the hands of those who have power to legislate. Act quickly."

At least 59 people were killed and more than 500 were wounded when a heavily armed gunman opened fire from his hotel room window onto an open-air country music festival on the Las Vegas Strip.
