Rihanna has been forced to cancel tonight's concert in the French city of Nice after a horrific terror attack that killed 84 people.
The singer was meant to perform this evening at the Allianz Stadium in Nice on the European leg of her Anti World Tour, but has had to pull out because of the awful tragedy.
Although it's still unclear what happened in the attack, it's thought a gunman jumped in a truck and sped through Nice, mounting pavements and killing revellers as they celebrated the historic Bastille Day.
He then stopped and took out a gun, shooting into the crowd as people fled in terror.
The death toll is still rising, and more than 50 people were injured before the driver was stopped and shot dead by police.
As well as Rihanna, the cast and crew of Fifty Shades Darker – including stars Jamie Dornan and Dakota Johnson – are safe and accounted for.
The film was being shot on location around the French Riviera, and Jamie and Dakota had been filming a scene in a boat in the nearby Saint-Jean-Cap-Ferrat just hours before the attack.
Movie producer Dana Brunetti tweeted confirmation that everyone from the film was safe, writing: "Back safe in my hotel room. Thanks for everyone's concern and messages.
"As far as I know everyone from our cast and crew is safe. Thanks for everyone's concern."
Our thoughts are with those affected by the terrorist attack.
