I'm not sure how far in advance it's filmed, but she was pregnant in real life and had a miscarriage a few months ago, so she probably needs a break.
Well, she's been back working at Coronation St since she had her miscarriage, but she's probably leaving it this time for her boob job.
It's bad enough that I know this shit, but the fact that I share it with strangers is probably even more worrying.
