Update: Ariana Grande Breaks Down in Tears During Manchester Benefit Concert
UPDATE (June 4, 2017 at 5:20 p.m. EST): Ariana Grande was not going to be deterred by another terrorist attack.
The pop star continued as scheduled with her One Love concert to benefit the victims of the recent Manchester terror attack, despite the occurrence of another deadly terrorist attack in London just last night.
The singer put on a brave face and a great show for the massive crowd, with all of the proceeds for the concert going toward the We Love Manchester Emergency Fund.
Ariana even dedicated the show to Olivia Campbell, 15, who was killed when the suicide bomb went off during her Manchester concert on May 22.
The 23-year-old had trouble holding back tears as she spoke of the slain teenager.
"Her mother told me Olivia wouldn't want me to cry and would have wanted to hear the hits," she told the crowd.
Also on hand to perform were megastars Justin Bieber, Katy Perry, and Miley Cyrus, among others. All performed free of charge, and all were appropriatedly overcome with emotion.
Justin, 23, had tears in his eyes as he told fans to "fight evil with good." Katy, 32, praised the bravery of those in attendence and professed the importance of love.
Miley, 24, joined Ariana for a duet, and the two shared a warm embrace as they held back tears together.
Read on for more of our original coverage of the London terror attack to find out how various celebrities responded to the tragedy.
Original story (June 4, 2017 at 10:54 a.m. EST): Ariana Grande is emodying the English spirit by keeping calm and carrying on.
The singer's June 4 concert to benefit the victims of the Manchester terrorist attack will go ahead as planned, despite the horrific attack that struck London on June 3.
Seven people were killed and another 48 injured when a van mowed down pedestrians on the London Bridge Saturday night.
Three men then got out of the van and began stabbing random patrons in the cafes at Borough Market before being shot and killed by police.
The attack came less than two weeks after a suicide bomber killed 22 people — many of them children — at Ariana's concert in Manchester, England.
But in spite of the continued threat of more terror attacks in the U.K., Ariana's manager Scooter Braun confirmed that the 23-year-old will still host her One Love concert in Manchester tonight as planned.
The "Side to Side" singer will be joined at the concert — which is raising funds for victims of the May 22 attack — by superstar acts like Justin Bieber, Katy Perry, Coldplay, Miley Cyrus, Pharrell Williams, and more.
All singers at the concert are performing for free in the hopes of raising as much money as possible for the 'We Love Manchester' Emergency Fund, while security has understandably been stepped up considerably for the event.
During the London attack, some bystanders reportedly fought back against the terrorists, hurling chairs and pint glasses in an attempt to stop the carnage.
And while devastating, the attack was over very quickly thanks to a quick police response, with all three suspects shot and killed by the authorities within 8 minutes of the first emergency call.
Still, the attacks understandably remain fresh on everyone's mind, including a number of celebrities who have expressed their shock and sorrow for the victims.
A terrorist attack in central London on Saturday night killed seven people, the third major attack on the U.K. in the space of three months. Prime Minister Theresa May described a "new trend in the threat we face" and said "enough is enough." Read more on TIME.com.

"My heart goes out to #London. So sad," tweeted Bethenny Frankel. "The world is such a scary place right now. Stay strong & stay safe, everyone."
Ariana Grande herself even took a moment out of preparing for her concert to voice her support on Twitter, writing, "Praying for London," alongside a heart emoji.

President Donald Trump used a different approach, taking to Twitter to first use the attack as an opportunity to promote his Muslim travel ban without offering any condolences to the victims.
In subsequent tweets, the 70-year-old former reality star continued to use the attacks to promote his own agenda; criticizing gun control, political correctness, and even London Mayor Sadiq Khan, who is Muslim.
