Matt Healy's mum Denise Welch had six hours of panic when she thought her son had died.
The singer, who fronts indie band The 1975, was angered by a Twitter rumour earlier this year that he had died of a drug overdose and his mum struggled to get hold of him to make sure it wasn't true.
He said: "Russell Brand had that he died in a snowboarding accident, that's quite funny.
"Someone said I had an overdose in my flat, who's making that s**t up? I didn't. I was on a plane to America.
"My mum rang me in tears. She thought I was dead for six hours. That's not cool at all. That is the s**t I don't like [about fame]."
The 25-year-old star, whose father is actor Tim Healy, has grown up dealing with fame but admits there have been a number of rumours about him and he isn't a fan of the attention that comes with his band's success.
Speaking at the Bushmills Live festival on Ireland's north coast, he exclusively told BANG Showbiz: "There have been loads of rumours. [One] that I slept with Rashida Jones, Quincy Jones' daughter, I didn't sleep with her. I wish I had. She's wife material."
He added: "I don't really like it [the fame] on a personal level. I don't like being so exposed and having things that I don't think about being topics of conversation for other people. I don't like the fact that every time I get out of a car I have a f***ing camera in my face.
"But, then again, I don't resent the element of fame that's marred my life because it's amplified the way I am as a writer. I kind of understand it, it makes me a better writer. But I don't want to be famous famous, I can't be arsed with that."
