The 23-year-old singer's scheduled concerts in Europe- including two in London's O2 Arena as well as all others until the one planned for June 5 in Switzerland - have been cancelled as Grande wanted to pay "proper respects to those lost", reported The Guardian.
"Due to the tragic events in Manchester, the Dangerous Woman tour with Ariana Grande has been suspended until we can further assess the situation and pay our proper respects to those lost," the tour's promoters confirmed in a statement.
Grande, who, hours after the attack, tweeted that she was "broken" and at a loss for words, returned to her home town of Boca Raton in Florida on Tuesday.
Her current 'The Dangerous Woman Tour' is in support of her third studio album, 'Dangerous Woman', which released last year on May 20. The tour began on February 3, in Phoenix, Arizona.
