Lorde has concerned her American fans with her latest admission.
The Kiwi pop star – whose real name is Ella Marija Lani Yelich-O'Connor - is touring America for her Solar Power world tour and while performing in Washington D.C last night she shocked fans by revealing her pre-show activity.
"I was lying in the Potomac River … I love to swim in the water where I'm playing, it makes me feel like I know you a bit better, somehow," the 25-year-old singer announced to an audibly and visibly horrified crowd.
While the activity may seem harmless to New Zealanders, NBC reported that the fans' horror is because the Potomac River is contaminated with bacteria such as E.coli, which can come from sewage overflowing from stormwater systems after heavy rain.
