Mel B brought a scary level of spice to Mel C‘s recent show … jumping onstage to perform a beloved Spice Girls song with her pal!

Sporty Spice — who released her album “Sweat” on Friday — had a show in Leeds Saturday night … and she brought out her former bandmate, a native of the area.

Mel B showered praise on her pal … saying she really enjoyed the performance to that point … before playing “Spice Up Your Life” with her friend.

It’s the first time the Mels have been onstage together since the last Spice Girls tour — which featured everyone from the group except Victoria Beckham.

While it’s a nice moment for the two ladies, a full-on Spice Girls reunion is still up in the air … with Mel B recently shooting down the idea.

Remember, she told Hello! last month that she wasn’t going to badger the other girls into getting the band back together … adding she’d be surprised if it happened.

Mel C, on the other hand, said last week that she hopes another reunion will happen … so these two seemingly do want to grab the girls and hit the road again.

Last time all five members of the group performed together at a major event was the 2012 Summer Olympics in London … though they did have a small reunion at Beckham’s 50th birthday in 2024.
