The character (played by Bonnie Langford) had sent her son Shakil (Shaheen Jafargholi) out of the house as she was expecting Max Branning (Jake Wood) to visit for dinner.
Bonnie was dressed to impress and stripped off when she thought Max was waiting at the front door.
Much to her surprise, landlord Masood Ahmed (Nitin Ganatra) had returned to Walford and entered through the back door to see her in her sultry purple attire and suspenders.
However, Masood soon ruined Carmel’s day even further by announcing he would not be renewing her tenancy next month. Could she be homeless at Christmas?
Fans of the show instantly took to social media after the 53-year-old actresses stripping caused a stir.
One viewer tweeted: “Channel hopping & caught Bonnie Langford wearing sexy clobber in Eastenders. Have I entered a parallel universe?”
“Masood is back! Bet he wasn’t expecting Carmel/Bonnie Langford in her smalls when he got home. Could have come home to worse though! #EastEnders,” posted another, as a third said: “Bonnie Langford in that gear made this episode #EastEnders.”
A fourth added: “@bonnie_langford my 17-year-old daughter just said ‘dad come and see what Bonnie Langford is wearing in Eastenders’ a quick rewind, wow you look one hot momma!”(sic)
“Carmel has a great body for her age! Puts some young’uns to shame! #EastEnders,” wrote another, as a sixth gushed: “Can we just take a minute to discuss @bonnie_langford in that outfit – hope I look that good when I’m her age! #EastEnders.”
Not all viewers were happy, with one positing in all caps to say: “I REALLY DIDN’T NEED TO SEE BONNIE LANGFORD IN A BASQUE AND STOCKINGS! #EastEnders.”
