Hannah Spearritt, the S Club 7 singer, has revealed she was homeless over Christmas and has spent the past six months living in multiple temporary homes with her family.
Spearritt, 41, said she had to move into a friend's office after being forced out by a landlord.
In the last six months, the singer has lived in four temporary homes with her partner, Adam Thomas, and their two children who are three and four-years-old.
Speaking to The Sun, Spearritt said they had no choice but to move after a landlord left them with two days to find a new place to stay.
"Our landlord needed the money and the property sold so fast," she said.
"What screwed us is we didn't have time to find another place. We had somewhere over Christmas but ran out of time before we could move in. It was just a couple of weeks.
"We were allowed to stay in our friend's office. We just used it as our living room.
"It was extra space. It was stressful but you deal with it, don't you? Especially with the kids."
She added: "People think we must all be millionaires but sadly it's just not true. It was what it was and we enjoyed ourselves at the time."
She said that the band's wages weren't anything "compared to the money being made".
In 2018, Paul Cattermole, another member of S Club 7, sold his Brit award for £66,000 after stating he had "bills to pay".
According to The Sun, Spearritt earned £150,000 a year when she was performing with S Club 7.
The band achieved chart-topping success from 1998 until they split in 2003 - however, they have since reunited for tours across the UK.
Spearritt went into acting after the band split, landing a role in ITV drama Primeval in 2007, and she performed in the West End a few years later.
The singer told The Sun she has also faced health issues and that her and her partner's café business has recently stalled.
"I had an illness that took it out of me and I hardly got out of bed in three months," she said.
"There have been delays with the café. The reasons are very personal. It's life stuff, and hard to explain.
"But ultimately we're still here. And the café will open. We're looking forward to the future."
Spearritt is the only original group member not to sign up for S Club 7's reunion shows, including dates at London's O2 Arena, this autumn.
She told The Sun that there was still a chance she would join her bandmates for the comeback shows but that it was dependent on her health.
