Emotional: Sacha Parkinson struggled to control her tears as she was interviewed about her Coronation Street exit today
They are as close off screen as they are on screen.
So it's no wonder that Sacha Parkinson found herself overcome with emotion as she was shown a montage of her Coronation Street romance with co-star Brooke Vincent during an interview on This Morning.
The 19-year-old actress, who plays Sian Powers in the ITV soap, held her hands over her face and told hosts Eamonn Holmes and Ruth Langsford 'I'm so embarrassed!' as the camera cut back to her after the montage showing her struggling to control her tears.

Real-life best friend Brooke then jumped in to continue the interview for Sacha, explaining: 'It's mad just looking at it. We've spent so much time together and preparing for it.
'We've been saying for ages that it's the beginning of the end but this is the end, that's it now.'
Brooke, who plays Sacha's girlfriend Sophie Webster in the soap, then added: 'I'm going to start crying now!'
Hiding: Sacha admitted she was emotional after seeing a montage of her on-screen romance with Brooke
Talking about her friendship with Sacha, Brooke said: 'We're more like sisters, we've done a lot together and we've known each other since we were about six.'
The duo were appearing on This Morning to talk about their upcoming Christmas storyline, which will see their wedding called into doubt after Sophie's affair with Amber.
And while details of the plot have yet to be released, the fact that Sacha is leaving the soap suggests things won't be going according to plan.

Talking about her plans post-Corrie, Sacha said: 'It's really exciting just going back to auditioning. It's just something I have to do.
'I was so comfortable there that I could have stayed there for the next 50 years but I just want to do something interesting, something to get my teeth into.'
But when Brooke was asked if she has considered leaving the soap for the same reasons, she replied: 'I don't like change - I don't like anything changing. I'm just happy and settled, I know my routine and I like that.'
