Ariana Grande sold-out Manchester Arena show may have specifically targeted by ISIS because of the singer's self-assurance and sexy, proudly feminine style, everything the terrorist organization despises.
Grande has a vibrant social media following, and her concerts are packed with young women and girls who admire her message.
Mubin Shaikh, a former extremist, believes ISIS viewed the attack as a kind of perverted "PR opportunity."
"To hit a den of immorality, as ISIS acolytes are calling it, it's a great target for them," he said. "Ariana Grande is a big name brand; the media will descend on it. Children being killed will get coverage, and that emotional reaction. So, all these things are hitting at the same time at the same place."
U2's Bono echoed that sentiment on Jimmy Kimmel Live Tuesday night.
"They hate music. They hate women. They even hate little girls. They hate everything that we love," the Irish rocker said. "The worst of humanity was on view in Manchester last night, but so was the best as people took perfect strangers into their houses and queued up at blood banks. Manchester has an undefeatable spirit, I can assure you."
Now, some of the biggest stars in pop music are saying their shows will go on despite the carnage in Manchester.
Photographers caught up to Nicki Minaj in Los Angeles where she said she will perform or else "they win."
Katy Perry says she'll perform as scheduled at Radio 1's Big Weekend in Hull, England.
"I think that the greatest thing we could do is just unite and love on each other, and like, no barriers, no borders, like, we all need to just co-exist," she told Elvis Duran on Z100 radio in New York.
Perry was blasted as "naive" by conservative commentator Michelle Malkin on Fox & Friends Wednesday morning.
"I think the next time we welcome refugees from Syria or Yemen to this country we should send them to her house," she said.
Justin Bieber is being flooded with pleas to cancel his upcoming concerts in England for his sake and the safety of his fans.
