Siobhan thinks everyone should stop giving Girls Aloud a hard time over their singing.
"I absolutely love Girls Aloud and wish people would stop slagging them off.
Some people have spread rumours saying they don't sing on their record - Sound Of The Underground - and this is really unfair.
Of course it's them singing ! No one else could sound exactly like Cheryl, Sarah, Nadine, Nicola and Kimberley.
One True Voice also became victims of another mean rumour saying they weren't singing on their song, Sacred Trust, either!
