Tina Barrett strips off in a photo shoot for this week’s ZOO Magazine.

The former S Club 7 hottie releases her new single Fire this month – a far cry from those S Club Party days way back in 1999.

“I’ve gone in a different direction and want to make an impact,” she tells ZOO. “In the video I’m a seductress and deeply saucy. I think it was about time!”

“Having come from a teenybopper group, I’ve now got the opportunity to be sexier, so I’ve been able to unleash my inner raunchiness. It’s like an explosion!”

Speaking about a potential S Club reunion, Tina revealed: “We’re all talking, so you never know. The critics would have a field day, but then they were critical of a Steps comeback and look how well they’ve done.”

More pictures appear in this week’s ZOO, on sale now (Tuesday).
