In the days since Ariana Grande‘s new album Eternal Sunshine dropped on March 8, one song on the 13-track set has quickly become a favorite amongst fans — Olivia Rodrigo included.
In a video shared to TikTok Sunday (March 17), the 21-year-old pop star dances along to Grande’s “The Boy Is Mine,” seemingly backstage at the Guts World Tour. As she twirls around and shows off her purple cowboy hat, a smiling Rodrigo sings along to the R.E.M. Beauty founder’s sensual lyrics: “The boy is mine/ I can’t wait to try him/ Let’s get intertwined/ The stars, they aligned.”
Shortly afterward, Grande took notice of the clip and shared it on her Instagram Story, adding a cute gif of a dancing cat holding a flower.
The “Positions” singer has also reposted videos of her “34+35” remix collaborator Megan Thee Stallion and Christina Aguilera using the ’90s-infused track in recent days. “love you,” she wrote in response to Xtina, alongside four teary-eyed emojis.
Led by singles “Yes, And?” and “We Can’t Be Friends (Wait for Your Love),” Eternal Sunshine recently debuted atop the Billboard 200, marking Grande’s sixth No. 1 entry on the chart. In an interview leading up to the album’s release, the 30-year-old vocalist told Apple Music 1’s Zane Lowe that she thinks of “The Boy Is Mine” as a “bad girl anthem,” explaining that “there is a large group of my fans that really, they do love a bad girl anthem.”
Rodrigo’s latest album Guts dropped in September and also debuted at No. 1 on the Billboard 200. In February, she kicked off her global Guts World Tour, which will find her making stops across North America and Europe for the next five months before she closes out with four shows at the Kia Forum in Inglewood, Calif.
