greatest diva seasons in pop history — from Ariana Grande’s “Eternal Sunshine” and Beyoncé’s “Cowboy Carter” to Taylor Swift’s “The Tortured Poets Department,” Dua Lipa’s “Radical Optimism” and Billie Eilish’s “Hit Me Hard and Soft.”But as we set summer off, there are no signs of diva fever cooling off, with the likes of Sabrina Carpenter, Gracie Abrams and Chappell Roan bringing that femme heat.And let’s not forget about Camila Cabello, who is back with her new album “C,XOXO,” out on Friday. It’s her fourth album since going solo from Fifth Harmony — and how the hell did that happen? Wasn’t she just, like, breaking up the group?Well, since then, she hasn’t exactly become the next Beyoncé.
