The pop collective - which featured Tozer, Claire Richards, 'H', Lee Latchford-Evans and Lisa Scott-Lee - scored 14 consecutive top five singles before splitting in 2001.
Tozer said that the five-piece now regularly speak and email each other, admitting that old tensions are now "water under the bridge" for the band.
"I would say that we are probably closer friends now than when we were together because we have more in common," she told DS.
"There is water under the bridge from back in the day and we are very supportive of each other. The girls have got kids now, so that makes it important to stay in touch. It's not something that we can brush aside because the band was such a huge part of our lives.
"We got together just after Christmas, end of January, and all had dinner around Claire's. It was really lovely."
The singer admitted that she used to "clash hideously" with 'H', but said that it was important to reconcile as friends because they had shared experiences.
She also revealed that the group had been offered numerous deals to reform, including representing the UK at Eurovision, but insisted that a reunion was not "in the pipeline".
"When one person gets an email from a telly person or company, we all send it to each other and discuss it as a team together, which is nice," she said. "And no, we're not getting back together to answer your next question. It's not in the pipeline."
