Girls Aloud slam songwriter Betty Boo

Girls Aloud have slammed 80s pop star and songwriter Alison 'Betty Boo' Clarkson for fuelling rumours the band was to split.

Singer Cheryl Cole insists Clarkson - who penned tracks for the British girl group's first album 'Sound Of The Underground' in 2003 - was lying when she recently claimed she had been approached to write solo material for the 24-year-old star.
