The 28-year-old "Hello" hitmaker revealed she is least bothered about the highly-publicised split as she barely knows the actors, reported AceShowbiz.
"I would like to say I think it's a bit sick you're reporting on an absolute joke. I don't care if they've broken up. They're making out like I was heartbroken and being like, 'Oh my god. I gotta dedicate...' I don't care! I don't know them," she said.
The singer said she does not get it why the news of their break-up is making front-page headlines.
