The group, formed by the Popstars in 2001, split just 18 months after their formation when their second album flopped. However, Shaw told The Mirror that the change of public opinion affected her bandmates including Kym Marsh and Myleene Klass more than it did her.
"When the backlash happened with Hear'Say it didn't affect me too much because I'd been auditioning for years and was used to rejection," she said. "It affected the others, though."
The Emmerdale actress admitted that she is a big fan of reality shows like The X Factor, but acknowledged that the pressure faced by the contestants and their families has increased.
"I love them,” she told the paper. "I think they're brilliant but I think the contestants must know what they're getting into. For us, Popstars was the first show of that kind and it was a learning curve - we were thrust into huge fame.
"Nowadays it must be up to the families and the contestants themselves to be responsible and know whether they are strong enough to cope with the pressure."
