Ariana Grande is "broken" by the deadly blast outside her concert in Manchester.
She tweeted, "from the bottom of my heart, I am so so sorry. I don't have words."
TMZ is reporting that Grande has indefinitely suspended her world tour and that she is inconsolable ... "in hysterics" after the bombing.
Ariana's manager, Scooter Braun, stated, "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."
This is so incredibly sad. More below.
