Hollywood star Margot Robbie and singer Delta Goodrem will appear in this week’s Neighbours finale.
They join 49 actors back for the last show – including its biggest former stars Kylie Minogue and Jason Donovan, both 54.
Margot, 32 – currently filming the Barbie movie – played the soap’s Donna Freedman from 2008-2011.
Her scenes famously included a same-sex kiss and Margot, married to British film producer Tom Ackerley, 32, hailed the show as “brilliant training”.
Delta, 37, played aspiring singer Nina Tucker in 2002.
Her hit from the show – Born to Try – made it to No1. Kylie and Jason’s 1989 Neighbours hit – Especially for You – is being re-released next week to mark the end of the show’s 37-year run.
The final episode will also feature Ramsay Street favourites Jesse Spencer, 43, Kym Valentine, 45, Alan Fletcher, 65, Jackie Woodburne, 66, and Carla Bonner, 49.
Jason Herbison, Neighbours’ executive producer, said: “We are beyond excited and feel very humbled that so many favourite characters are here with us – and there are more surprises to come on the final night next week!”
The final episode is on Channel 5 at 9pm on Friday
