Amy Winehouse was not rushed to hospital on Monday evening because a friend spiked her drink with ecstasy, her father, Mitch, says.
A source, apparently close to Mr Winehouse, told today's Sun newspaper that he was “certain” someone had spiked his daughter's drink.
The paper also quoted the source saying that Mr Winehouse was “determined to get to the bottom of it.”
However, speaking to the BBC, Winehouse's father denied ever saying that, adding: “And I don't know who this source is. But I'm gonna find out."
Winehouse was taken to hospital by ambulance and kept under observation overnight after falling ill at her home in Camden.
Her spokesman said yesterday that the singer had suffered a reaction to medication.
Mr Winehouse added today that his daughter was “doing just fine.”
