Kylie Minogue has been joined on stage by her former Neighbours co-star Jason Donovan during her headline show in London's Hyde Park.
Minogue was top of the bill at BBC Radio 2 Live show on Sunday, where she performed her and Donovan's 1989 hit duet "Especially For You".
Midway through the song Minogue said "I need a dance partner" and Donovan came out on stage, picked her up and spun her around.
Minogue performed a few of her older hits during a brief technical difficulty treating the crowd to introductions from songs including "Step Back In Time", "Locomotion" and "I Should Be So Lucky".
After Donovan twirled her around on stage and the pair embraced, she told the audience: "Where do we go from there? I had no idea that was going to happen!
"Thank you Jason. We travelled back on time there."
Minogue also was joined by Rick Astley to sing his hit "Never Gonna Give You Up" and "Kids", the duet she originally released with Robbie Williams.
Minogue, who celebrated her 50th birthday in May, said both Donovan and Astley had been at her party to mark the occasion, adding: "50 happened this year and for more than half of those years I've been with quite a lot of you."
She went on to thank her fans for sticking with her through "the ups, the downs, the middle of the road, the got it right, got it wrong".
