Ariana Grande’s extensions must have grown three sizes the day she found out she was collaborating with Kristin Chenoweth. And not only collaborating, but working together on a song from Ari’s movie obsession, The First Wives Club. Who can forget the staging of “thank u, next†on Ellen, 100 percent by and for the Wive Hive? Or when she got engaged to Pete Davidson, but mainly wanted to tweet about Wicked? The duet between Grande and Galinda was announced in August, when we got deets for Kristin Chenoweth’s new album. For the Girls dropped at midnight Thursday night. Other musical pals on the album include Dolly Parton, Jennifer Hudson, and Reba McEntire.
