Kylie Minogue reportedly slapped her boyfriend during a public blowout in New York City last week.

The 41-year-old Aussie singer is accused of wacking Spanish model Andres Velencoso — 10 years her junior — in the face during an argument outside the B Bar.

An onlooker told PageSix: “At some point, Kylie and Andres got separated. When Kylie found him, she slapped him in the face with a fan. Then she yelled at him for making her wait outside while he stayed inside and got another drink.”

Despite whispers of trouble in paradise, the “Locomotion” singer is reportedly considering converting to Catholicism so she can have a traditional church wedding to Andres.

The couple began dating last November.
