Selena Gomez attends Ariana Grande's special Eternal Sunshine tour stopSelena Gomez and Benny Blanco showed up to Ariana Grande's London tour stop for Eternal Sunshine tour this weekend, as she delivered a special performance. The 33-year-old pop superstar invited her pal and Wicked co-star Cynthia Erivo to perform For Good together, and made the show memorable.  The Only Murders In the Building star was also spotted grooving to the music, and dancing from time to time with her husband.  While fans were excited to see Grande and Erivo together, they were also starstruck to see Gomez in the crowd. Sharing the videos from the night, fans took to social media and wrote, "Oh mothers," and "BRING HER ON STAGE TO PERFORM PETAL REMIX." A third chimed in, "Queen attending another Queen we love both," and "THANK YOU ONLY MURDERS IN THE BUILDING," as Gomez is in London for the filming of the show. Another gushed, "An Icon supporting an icon."
