The 30-year-old took to Twitter to reveal he'd pulled the girl and her father from the car, after witnessing the 'horrific' motorway accident.
He wrote: "Just witnessed the most horrific crash on the m60. I ran to the car to see a family of 4. I pulled a little girl and father from the wreckage."
Now former X Factor winner Shayne has urged his followers to help him find the family so he can make sure they're ok.
"Can everyone please retweet this in the hope it reaches relations of the family," he continued.
"As I've tried to contact different hospitals in Manchester… but no luck so far. I hope they're all ok! [sic]."
Shayne's message has been reposted almost 600 times, but it is not know whether he has managed to locate the family.
Brave Shayne is the latest star to join the line-up of Coronation Street, following in the footsteps of Sarah Harding and Paddy McGuinness.
It's been confirmed that he will be playing Michelle Connor's cousin Aiden and he's set to make his debut on the soap later this year.
