The former Coronation Street actor won a large number of fans during the show.
She appeared on the show from 2011 to earlier this year, playing the blond bombshell Eva Price.
Since leaving the show, the 35-year-old girl has been turning her attention to fitness.
Catherine often shares her workout snapshots on the official Catherine Tyldesley Instagram page.
Catherine had frankly talked about her weight loss journey after she admitted that she had lost more than five stones before her Corrie debut.
But she exchanged a fitness button today to return to the photo because she shared her own photo and the elves of her previous Corrie star.
The two actresses collaborated with Lisa George to play Beth Tinker in a long soap opera, and the two actresses became popular actresses.
Lisa brought her inner Britney to the iconic Baby One More Time female student to get up.
Catherine chose the dressing choice of the popular Madonna Queen.
She looked sensational when she swayed Madge’s signature conical bra corset.
Catherine took her look and went all out, even pulling her hair into a curly high ponytail.
Madonna shocked the famous Jean-Paul Gaultier underwear in the Marilyn Monroe stage of the early 1990s.
It was sold at the 2012 auction for up to $52,000 (£40,000).
The fans clearly believe that Catherine competed with Madonna and Marilyn in the photo because they had a fierce compliment.
One fan said: “Although it still looks hot.”
And the other continues: “The heroine Eva.”
The third screamed: “This will definitely make my face smile.”
