Who Is Performing at the Summertime Ball 2026の全体像を詳しく解説してご紹介します。

Here’s where it gets weird and wonderful. The Spice Girls are reuniting for one song only. That song? “Wannabe.” But here’s the kicker—they’ll be joined by Dua Lipa for a mashup with “Levitating.” Girl power just got a quantum boost.

Also confirmed: ABBA’s hologram tour is making a pit stop. Yes, the digital versions of Agnetha, Björn, Benny, and Anni-Frid will perform “Dancing Queen” while actual disco balls rain from the ceiling. It’s going to be chaos. The best kind.
