One Direction shouldn't tackle songwriting because it could be the "kiss of death" for them, Cathy Dennis has said.
The award-winning songwriter - who has penned top tunes for the likes of Britney Spears and Katy Perry - thinks Harry Styles and co should stick to doing what they do best, reported The Sun.
She said: "It will be expected that they will write their own songs at some point. Someone is going to say, 'Hang on, the royalties coming in from just singing are not enough'. The guys who wrote What Makes You Beautiful are millionaires.
"But if 1D started writing their own songs it could be the kiss of death, let's face it. I am not going to advocate that. To emulate the Rolling Stones - you can't have that overnight."
Cathy, whose best known songs include Kylie Minogue's massive hit Can't Get You Out Of My Head, added that she wouldn't expect the boy band to come out with "anything amazing".
The boys are all thought to be keen on penning music. Harry said last year: "I think we all write. On the road and stuff we're in a lot of planes and in a lot of hotels and obviously you just write there."
