During her Australian and New Zealand tour, Adele is performing stadium concerts in a 360-degree production created to make the huge show feel intimate.
It's not the first time the singer has called a drag queen impersonator to the stage.
Adele delivered another surprise on her 25 world tour by inviting a drag version of herself on-stage.
Fans in the 65,000 audience filmed the impersonator belt out some lines from Adele's hit Rumour Has It as the singer clapped and danced along, then asked for a selfie.
"I impersonate you professionally for a job", Feminem told Adele in front of an audience of thousands.
"I just spent $700 on this dress", she told Adele, as she joined her onstage wearing an almost-identical custom made sparkly number to the popstar. The singer complemented her and even said she looks better than her.
"But I felt the need to say that because I love her and I felt like she was more worthy".
Feminem was even courageous enough to ask the superstar if she could perform for her.
This is the first time 28-year-old Adele has performed in Australia, and unsurprisingly, the Grammy victor is already a massive hit.
'And then when she came further and was walking down the catwalk, she circled the stage she stopped and she said 'I want to meet you.' And security did the rest, ' she explained. "I know it's my first one here - who knows if I'll tour again - but I'm in here now and I love it and you look f--ing lovely".
She told the crowd: "The weight is going to fall off of me on this tour. I hope it was worth the wait".
