In scenes shot earlier this summer, Lily can be seen starring alongside actor Matthew Werkmeister, who plays Zeke Kinski, the host of PirateNet radio station.
She is interviewed by the 17-year-old actor before singing her new single 22, from her second album, It's Not You, It's Me.
Also appearing in the sequence is Neighbours favourite Dr Karl Kennedy – played by Alan Fletcher. And Lily had the chance to get up close and personal with one of Ramsay Street's most famous residents.
"Me and doctor Karl get our flirt on," Lily wrote on her Twitter page at the time of filming. "Quite funny."
The British brunette's visit to the soap's set took place in June while she was on tour in Melbourne. And, as well as causing much excitement among her co-stars, the experience left Lily pretty star struck.
"Neighbours, everybody needs good neighbours," she tweeted at the time. "OMFG! Just saw Paul Robinson and Libby Kennedy."
Lily's guest slot follows appearance from fellow stars including Michael Parkinson, Emma Bunton, Matt Lucas and David Walliams.
She will be seen on British TV screens on November 10 on Five.
