Coronation Street fans are gobsmacked after learning the age gap between actresses Sue Nichols and Helen Worth.
The actresses joined the ITV soap in the 70s as mother and daughter Audrey Roberts and Gail Platt.
And it is safe to say they haven't had the easiest relationship over the years, with a number of shocking storylines between them including Audrey's drinking.

Audrey even found herself caught up in a murder plot and, late last year, she was drugged by her evil son Stephen Reid.
However, Stephen backed out of his evil plan and Audrey was recently seen heading on a trip away from Weatherfield.
Over the years viewers were distracted after realising that Sue is 79 and Helen is 72 - meaning that there is only a seven-year age gap between them - The Mirror reports.
One viewer tweeted: "Helen Worth is 71, born January 1951 Sue Nicholls is 79, born November 1943 Therefore Audrey gave birth to Gail when she was seven years old... scandalous! #Corrie".
While another commented: "They both look amazing!"
A third wrote: "They both look great for their age!"
Another said: "Mad thing now is Gail and Audrey look about the same age #Corrie," while a fourth replied: "There's only about 7 years between them in real life".
Helen is set to mark 50 years on the soap next year and is the second longest-running star on the show after she started the show in 1974.
She was also awarded with an MBE for her services to drama by Prince William earlier this year.
Meanwhile Audrey actress Sue has continued to address hard-hitting storylines as Audrey attempted to take her own life last year.
As the heartbreaking scenes of Audrey's suicide attempt aired, actress Sue said: "Now that is the message that I want people to take away from this storyline, the importance of being able to talk to people you trust about how you feel.
"Sometimes the young generation might think that anyone over 70 isn’t capable of making decisions which in turn can make older people lose their sense of purpose and begin to feel quite useless."
William Roache is the show's longest running character as he's played Ken Barlow since the show first aired on 9 December 1960.
