TRUMP CURSE: Ariana Grande and Pete Davidson Split, Call Off Engagement

The romance between "Sweetener" singer Ariana Grande and "SNL" performer Pete Davidson has turned sour.

The couple, whose whirlwind romance-turned-engagement powered the celebrity gossip machine through the summer, has split, a source close to the singer tells CNN.

Davidson confirmed their engagement in June. They had been dating a few weeks at the time.

[...]In an August interview with GQ, Davidson called himself "the luckiest guy in the world."

"The day I met her, I was like, 'Hey, I'll marry you tomorrow,' " Davidson recalled. "She was calling my bluff. I sent her a picture [of engagement rings]. I was like, 'Do you like any of these?' She was like, 'Those are my favorite ones,' and I was like, 'Sick.' "
