Nine-year-old Lilly shot her non-speaking role on the ITV soap earlier this week, just a few months after she toured the set with her footballer dad Steven.
Mum Alex tweeted her a good luck message beforehand, saying: "Good luck to my little girl Lilly at Coronation Street today. Hope it goes well!"
Alex later told a follower: "She done well… she loved it x."
A source told The Sun: "It's only a little, non-speaking role but the whole Gerrard family are unbelievably excited. It should be on screen in around six weeks."
Liverpool captain Steven took Lilly and middle daughter Lexie for a visit to Weatherfield in February 2013, where they met some cast members and toured the set. Apparently that's where Lilly picked up the acting bug, leading to her Corrie cameo.
We'll be keeping our eyes peeled!
