Fans of the Spice Girls who have got tickets to their reunion tour could be in for some very special surprise performances - including one with Adele.
The nineties pop group sensation will play their first live shows in 20 years next summer, kicking off in Dublin on May 24th.
Victoria Beckham has said she won't be performing with the band again, but it is hoped she will make an appearance at some stage during the tour.
The remaining four Spice Girls have been looking at the possibility of getting guest performers to stand in for Posh "for a song here and there".
Speaking on Jessie Ware’s Table Manners podcast, Mel B said they have been talking about "getting other people on stage with us."
“Katy Perry has agreed to do it — hopefully Adele will do it.”
Adele is known to be a huge Spice Girls fan, giving them shout outs during her own live shows, and posting this excited photo when the band confirmed their reunion tour.

Mel B has also revealed the Spice Girls are in talks about performing at Glastonbury.
"It’s been talked about. But we’re so pop and it’s so cool — that’ll be funny to me", she told Jessie Ware's Table Manners podcast.
"I think Mel C would really appreciate us doing that — she’s the cool one. She’s the cool indie chick."
