But it looks like their hit song "Feels" has inspired just that...
According to Life & Style, Katy is all too keen on dating Calvin now.
"Katy blushes whenever she’s with Calvin because she thinks he’s so hot,” says a source. “She loves his accent and his sense of humour. She’s told friends that she’d love to go on a date with him.”
Although they have apparently pushed that they wouldn't date for revenge purposes, the source has admitted that, "Calvin and Katy have joked that they’d love to see Taylor’s face if they hooked up."
Ooooh the drama.
Would you guys like to see Katy and Calvin hook up?
