Ariana Grande reacts after Manchester concert attack kills 22 people

Late Monday evening, Ariana Grande finished a Manchester concert as part of her "Dangerous Woman" tour. Shortly after, a bomb detonated, killing 22 individuals and injuring scores of others. According to the Guardian, the youngest victim has been identified as eight-year-old Saffie Roussos.

The pop star soon tweeted to express her feelings, though Grande has yet to make an official public statement.

The tweet, posted at 10:51 PM on the day of the attack, has been liked over two million times and retweeted over one million times. For comparison, Grande's other recent tweets have averaged between 8,000 and 50,000 likes and retweets.

Grande is known for her bubblegum pop music and easy-going persona. Her career gained traction in 2009 when she starred as the bright-red-haired space cadet Cat on Nickelodeon's "Victorious." Audiences fell in love with her bubbly personality, powerful voice, and sparkling red hair, which she has since stopped dyeing due to the damage it caused to her naturally brown locks.

While Grande has continued to utilize her lighthearted image since "Victorious" ended, it may be hard for her to maintain after Monday's attack.

An outpouring of support for Grande and all those touched by the tragedy

While Grande's tweet marks radio silence since the attack, support has poured in for star -- as well as the victims. Shawn Mendes, an 18-year-old Canadian pop singer, showed an image of a ribbon with Grande's signature animal ears at his Wednesday night performance to show support for Manchester and for Grande.

A number of other artists, such as Britney Spears, Little Mix, and Celine Dion, have displayed similar public messages via Twitter/during their own concerts.

Although Grande has suspended her "Dangerous Woman" tour until June 5, stars such as Nicki Minaj and Mendes have promised fans that they will not cancel their concert tours in Manchester due to the attack.

When asked by a TMZ reporter, Minaj stated, "Of course I'ma perform for my Manchester fans. They deserve it." Minaj also referred to Grande as her "sister," and stated that the attack was "heartbreaking."

While it's certainly good for these stars' public images to support victims of terrorism, the heartwarming displays of affection have touched a number of fans, as the support shown for Ariana Grande and her fans has certainly helped Manchester (and Grande's fanbase) heal since the attack.
