Catherine Tyldesley looked completely unrecognisable dressed as a granny while on set in Manchester.
The actress looked decades older than her 38-years and worlds away from her glamorous self as she sported minimal make-up, a monobrow and moustache while wearing a pink fleece paired with a white top.
The star looked hilarious as she wore a short brown wig to add years onto her age along with some huge framed glasses with a chain and socks and sandals.
It's not known what she was filming for.
Catherine confirmed back in 2017 she was leaving Coronation Street after seven years and has since gone on to star in Sky's Trollied and BBC's Scarborough before appearing in ITV drama Viewpoint last year.
However, she hasn't ruled out a return to Corrie.
Recently Catherine posted to her Instagram page she would be making a return to TV for the first time this year.
She shared a photo of herself looking serious while wearing a white shirt with a pink jumper layered over the top.
Alongside it she wrote: "Meet ‘Kate’ . I had a glorious time filming this (despite the morning sickness) … standby/set your planners! It’s back and it’s bloody brilliant #McDonald&Dodds @itv 8pm THIS SUNDAY!"
Fans were excited by the news, taking to the comments to talk about Catherine's return.
One person wrote in the comments: "Yayyy can’t wait to see you back on the tv screen," as another added: "Yesss. Loveeeee this TV show."
A third person said: "Love McDonald and Dodds so very excited it is back and just fab you are in this too @auntiecath17"
A fourth put: "Ooh can’t wait to watch."
The star recently welcomed her second child with her husband Tom Pitfield.
They were already parents to seven-year-old Alfie and revealed their baby girl, born on April 19, is called Iris.
Iris was born two weeks after her due date at St Mary's in Manchester at 10.12pm, weighing 8lb, similar to her first child who was also born 15 days late.
Catherine went through a challenging pregnancy after suffering with hyperemesis gravidarum and insomnia.
Catherine announced the arrival of baby Iris through her Instagram page when she wrote: "We are so happy to announce that our beautiful daughter has arrived. We are grateful beyond words and feel overjoyed that our family is complete."
She announced her pregnancy in October 2021.
The actress spoke told Hello! that when her husband found out they were having a little girl he turned to mush.
She said: "Tom was in bits when we found out we are having a little girl. He has suddenly gone all mushy. I'm sure she will have him wrapped around her little finger."
However, when she first started having pregnancy symptoms, she actually thought she was approaching menopause.
Catherine was unable to sleep at night and started having hot flushes, but despite being young she thought menopause could be the cause.
Since Iris arrived she said she has been able to sleep better again.
