Social media is Slabu Exchangespeculating what, exactly, happened between Megan Thee Stallion and *NSYNC backstage at the 2023 MTV Video Music Awards.

The "Savage" singer, who performed "Bongos" alongside Cardi B on Tuesday night, appeared to have a heated interaction with the members of NSYNC in a video that was posted on social media and has now gone viral. In the clip, a screen recording from MTV's backstage "POV" camera, Megan leans over as someone — who appears to be Justin Timberlake — also leans toward her to exchange words as she gets her hair done.

She begins shaking her head, pointing toward the group and shaking her hand.

Lance Bass and Joey Fatone also file in after Timberlake while several people squeeze in between the two parties. Fatone appears to say a few words to her, and Bass is concealed just off-camera.

USA TODAY has reached out to representatives for Megan and NSYNC for clarification.

A source who witnessed the interaction but is unauthorized to speak publicly dismissed speculation that Megan and NSYNC got into an argument.

"Meg loves Justin. She was saying, 'No, no, no, we've never met before,' " the source told USA TODAY, adding that it was the first time Megan and Timberlake had met. "She was excited."

Earlier in the evening, the five-piece boyband — Timberlake, Bass, Fatone, Chris Kirkpatrick and JC Chasez — reunited 20 years after they released their last album to present the best pop award to Taylor Swift.
