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.”

Naturally, the tweets drove Arianators into overdrive, with many pointing to another possible clue: The pop star recently sampled ‘NSync’s 2000 album cut “It Makes Me Ill” on her single “Break Up With Your Girlfriend, I’m Bored.”

“If ariana will bring out sync during her coachella performance.. consider me dead,” one fan tweeted. Another wrote, “Maybe Ariana can be the one to reunite *NSYNC.”

A third Twitter user echoed, “Calling it right now *nsync makes an appearance in ariana’s coachella set.”

Justin Timberlake, JC Chasez, Joey Fatone, Lance Bass and Chris Kirkpatrick formed ‘NSync in 1995. They went on to release three studio albums, including the record-breaking No Strings Attached, before splitting up in 2002. The band reunited for a one-off performance during Timberlake’s career-spanning medley at the 2013 MTV Video Music Awards and more recently received a star on the Hollywood Walk of Fame.
