Ariana Grande, Cynthia Erivo Reunite Onstage at London Concert

Ariana Grande and Cynthia Erivo proved their “Wicked” run isn’t over for good … reuniting for a surprise performance in London.
Cynthia joined Ariana during Sunday’s “Eternal Sunshine” show at the O2 Arena, where the costars performed “For Good” before launching into “Get Happy / Happy Days Are Here Again.”

The two embraced as the crowd went wild … marking their first performance together since last November’s “Wicked: One Wonderful Night” TV special, where they sang the same two numbers.
Cynthia had already revealed she planned to attend one of Ariana’s London concerts … but apparently she wasn’t content watching from the crowd.
The reunion came during the second show of Ariana’s 10-night run at the O2, which will bring her tour to a close September 1.
Oz may be in the rearview … but Ariana and Cynthia seemingly haven’t sung their last note together.
