Los Angeles, CA (YC) – Sources connected to Ariana Grande’s agent told YC Monday night that she will not perform Thursday in London and might’ve indefinitely canceled her world tour.

Ariana’s manager, Scooter Braun, said, “We mourn the lives of children and loved ones taken by this cowardly act,” adding, “We ask all of you to hold the victims, their families, and all those affected in your hearts and prayers.”

The pop star released the following statement on social media, expressing her solitude and apologies to those impacted: “broken. from the bottom of my heart, i am so so sorry. i don’t have words.”
