Selena Gomez's AMAs Performance Causes Twitter Frenzy as Some Viewers Accuse Her of Lip Syncing

Selena Gomez bravely returned to the stage Sunday night at the American Music Awards just months after her kidney transplant, but her performance is receiving criticism from viewers who claim she lip synced.

After singing her hit single “Wolves” while wearing a sexy slip dress, sneakers and Tiffany necklace, the star, 25, appeared subdued as she shrugged slightly at the applause and mouthed “Thank you.”

Her fans, however, clapped back at the haters.

“May i remind y’all selena is still recovering from a kidney transplant and she just gave the performance of a lifetime. words can not express how emotional i’m feeling right now. literally shaking,” wrote one loyal fan.

The star, who debuted a new blonde ‘do on the red carpet earlier in the day, appeared to leave the show before it was over and thanked her fans for their support on her Instagram story.

“So endlessly grateful to have been able to direct this,” she wrote on Instagram. “Thank you @selenagomez for being such a bad ass strong woman.”
