Rihanna's personal chef was just metres away from the famous Promenade des Anglais, where 84 people were killed in the terrorist attack. Debbie Soloman − who was in the French city with the songstress − revealed in an emotional Instagram post that she was left shaken by the events of Thursday evening ( 14 July).

Scores of spectators were killed and nearly a hundred injured, after a truck ploughed into a large crowd of people celebrating Bastille Day. The driver− named as Tunisian-born Mohamed Lahouaiej Bouhlel − drove 2km (1.2 miles) along the city's Promenade des Anglais, before being shot dead by police.

"After a beautiful day in Nice. It ends with tragedy right in front of our hotel. No one can either get in or out. And it's being reported that they're hostages," Soloman told her 23.1K followers. "I am happy everyone in our group is safe and accounted for but my heart goes out to all the families who now have to deal with all the heartache."

RiRi was in town because Nice was the next stop on the European leg of her #ANTI World Tour and she was scheduled to play Nice's Allianz Riviera Stadium on Friday (15 July) night. The 28-year-old songstress cancelled the show in the wake of the Bastille Day attack. She is still scheduled to perform in Frankfurt, Germany on Sunday 17 July.

In a message posted on her Instagram page she told fans: "Due to the tragic events in#Nice, my concert scheduled for tomorrow July 15 at Allianz Stadium will not be going ahead as planned. Our thoughts are with the victims and their families."

Meanwhile, celebrities are urging people to donate to the #giveforfrance crowdfunding effort. The fundraising campaign was started by the Foundation de France, France's largest grant-making charity, in the wake of the November 2015 terrorist attacks in Paris.

Orange Is the New Black star Ruby Rose told her followers she would lead by example by "donating my fee from the Electrobeach Festival today in France to #giveforfrance to help the victims of yesterday's awful tragedy."
