Ariana Grande has been on a ‘90s kick as she gears up for her upcoming headlining performance at the 2019 Coachella Valley Music and Arts Festival.

TMZ confirmed on Friday, April 12, that the “Thank U, Next” singer, 25, will be performing with ‘NSync, sans Justin Timberlake, in Indio, California, on Sunday, April 14.

The pop star shared two boy band-inspired videos on Twitter one day prior, which led fans to speculate that they may be her special guest when she hits the stage.

Ariana first tweeted an adorable throwback video of her mom, Joan Grande, holding her as a child in the audience at ‘NSync’s July 1999 concert in Sunrise, Florida.

An hour later, the Grammy winner uploaded a current video of herself doing the original choreography from the group’s 1997 single “Tearin’ Up My Heart” in her dressing room. “The best medicine,” she captioned the clip. “90s baby.”

Ariana’s longtime manager, Scooter Braun, has also been fueling speculation about her festival gig. On Wednesday, April 10, he cryptically tweeted, “Coachella you have no idea what’s coming!!!!” The next day, he responded to Ariana’s video from the 1999 ‘NSync concert, writing, “Little Ari and Nsync 🙂 #tbt.”
