Hannah Spearritt, the former S Club 7 star from Norfolk, has revealed that she and her family have spent the last six months living in temporary homes.
The 41-year-old singer from Gorleston also had to move into an office over Christmas and the New Year after being forced out by her landlord.
In an interview with The Sun, Spearritt said: "Our landlord needed the money and the property sold so fast.
"We ended up with under two days to leave.
"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."
She said they were allowed to stay in their friend's office, which they used as their living room.
"It was extra space. It was stressful but you deal with it, don't you? Especially with the kids."
Spearritt said public perception of her and fellow bandmates as "millionaires" was "just not true".
She added: "It was what it was and we enjoyed ourselves at the time."
Spearritt also told The Sun she had come down with an illness that had left her bedbound, while her and her partner's new cafe venture had also stalled.
After winning a place at the National Youth Music Theatre, Spearritt – who attended Lynn Grove High School and East Norfolk Sixth Form College, both in Gorleston – honed her acting skills with roles in Pendragon, Tin Pan Ali and the West End musical Bugsy Malone.
She was just 18 when she was thrust into the spotlight as a TV and pop star adored by millions of fans, when she scooped a place in a new pop group that was being put together by former Spice Girls manager Simon Fuller.
S Club 7 went on to have worldwide success, with hits such as Reach, Never Had a Dream Come True and Don't Stop Movin', as well as starring in their own TV series, before they split in 2003.
According to The Sun, Spearritt earned £150,000 a year when she was performing with S Club 7.
She is the only original group member not to sign up for the group's reunion gigs, including shows 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.
