Traumatised celebrities have tweeted about the “unimaginable” horror they witnessed in Las Vegas following the deadliest mass shooting in US history.
At least 50 people were killed and more than 200 injured after a gunman opened fire on concert-goers from the 32nd floor of the Mandalay Bay Hotel.
British tennis star Laura Robson said she was safe but "in shock" following the attack on fans at the open-air Route 91 Harvest Festival.
“I'm okay. We were right there... sounded like fireworks at first then everyone started running. Scary,” she wrote.
“My friend who was deeper in the crowd has been helping people who were shot. We're all in shock.”
American poker player Dan Bilzerian, the so-called King of Instagram, posted a video of him fleeing from gunfire at the festival.
“Holy f--k, this girl just got shot in the f-----g head. So f-----g crazy,” he said.
The 36-year-old said he grabbed his gun and headed back to help, adding: “It’s so crazy, some kind of mass shooting. Guy had a heavy caliber weapon for sure.”
Singer Jason Aldean, who was on stage when the shooting happened, wrote: “Tonight has been beyond horrific.”
Joe Wicks, The Body Coach, said he was safe in his hotel:
