Kylie's lesbian kiss.

Why is Kylie Minogue kissing Elvis’ granddaughter?

That’s a great question.

Turns out the 44-year-old actress/singer is filming a new indie movie called Jack and Diane, where she plays a tattooed lesbian who seduces a teenager.

This from the Herald Sun:

She plays Tara, who appears to be seducing Jack, played by Elvis Presley’s granddaughter, Riley Keough, in the coming horror romance.

In the film’s trailer, Minogue’s character walks over to a bruised Jack (Keough) and asks her: “Why did you come here tonight.”

Leaning in to kiss her, Jack replies: “I don’t know.”

The movie’s out in November.
