Natalie Cassidy was left red-faced during Tuesday afternoon's Loose Women as she made a confession about her personal hygiene.
The EastEnders star, 41, stunned Coleen Nolan, Kelle Bryan and Charlene White into silence when they misheard a statement she made.
Natalie appeared on the Daytime TV show as a guest panellist and at one point discussed opinions on a bidet.
A bidet is a porcelain bowl often situated next to a toilet, designed to wash other regions.
The actress said: 'I like a bidet, it reminds me of my family bathroom when I was little. Mum and dad’s bathroom, there was always a little bidet there.
'I haven’t got a bidet now but I do sometimes – on a warm day when I haven’t got time for a shower – fill up the sink and have a flannel wash.'
But when discussing her views of the European feature, Natalie horrified the panel when they misheard the world 'flannel'.
After quickly realising what Natalie really meant, Kelle, in stitches of laughter, said: 'She said flannel wash'.
Charlene added: 'Oh! Flannel wash! Few!'
Coleen joked: 'Oh I wish you would have said the other one!'
Natalie shouted: 'FLANNEL!'
After audience members and panellists gasped in shock before realising, it seems fans at home also heard the mistaken word behind screens.
Some viewers commented on X: 'Did she say f**** wash?', 'I legit thought Natalie Cassidy said a 'f**** wash'.
It comes after Ricky Gervais delighted fans by teaming up with Natalie for his first show since his widely-popular comedy-drama After Life.
The comedian and actor, 63, is reportedly working on an animated series about cats, with Natalie lending her voice to the new project.
A TV insider told The Sun: 'The project is still in its early stages, but Ricky is super excited as he's always wanted to make a show about cats.
'He's a big animal lover, so mixing comedy and pets is an ideal combination. And with his star cast on board, it's bound to be hilarious.'
According to the publication, a voice recording session took place in London last week and The Office star has signed an exclusive deal with Netflix.
Aside from the details of it being an animation that features animal characters, and revealing some cast members, Ricky is largely keeping the project under wraps.
The Office actor shared a sneak peek snap on his Instagram page capturing Natalie alongside the cast of the Netflix series including Kerry Godliman, Diane Morgan, Tom Basden and Tony Way, as they are all seen inside a recording studio with scripts.
'Look at this lot,' Ricky captioned and the soap star commented thrilled: 'Best day ever.'
EastEnders actress Natalie, who plays the character of Sonia Fowler in the popular soap, had previously described the comedy alum as her 'god' and admitted she was 'desperate' to meet him.
