Original Sugababes member Siobhan Donaghy insists the pop group never experimented with drugs during their early days of fame because their parents were always around.

Donaghy, Keisha Buchanan and Mutya Buena were aged 15 and 16 when the group leaped to fame in 2000 with their debut song Overload, but managed to steer clear of narcotics within the music industry.

Donaghy says, "We never got into it because our moms were there."

The redhead star quit the band in 2001 and has since started a solo career.
