Ariana Grande showed her support for London on Saturday night after two possible terror attacks left at least six people dead in the city. 

The singer’s message, sent on Twitter, was simple: “Praying for London ♡” 

Police are investigating after suspects plowed a van into a group of pedestrians on the London Bridge, then fled the vehicle and began stabbing people in a restaurant at the nearby Borough Market. At least six people were killed in the attacks and at least 30 were hospitalized.

The violence in London struck less than two weeks after a deadly terrorist attack hit Manchester Arena, where Grande had just performed. A suspected suicide bomber detonated an explosive outside of the concert, killing 22 people ― many of whom were children. 

Grande tweeted shortly after the Manchester attack that she was “broken” over the violence that followed her concert.

“From the bottom of my heart, I am so so sorry. I don’t have words,” she wrote.

The pop star announced days later that she would host a One Love Manchester benefit concert featuring an all-star lineup including herself, Katy Perry, Justin Bieber, Coldplay and Pharrell Williams. 

The concert sold out in less than six minutes. It is still scheduled to run at the Emirates Old Trafford in Manchester on Sunday.
