A newly blonde Gomez hit the stage at Los Angeles' Microsoft Theater in a short white nightgown and sneakers for her first performance in more than a year.
After the performance, her fans came to Selena's defense, with one tweeting, "may i remind y'all selena is still recovering from a kidney transplant and she just gave the performance of a lifetime. words cannot express how emotional i'm feeling right now. literally shaking".
Viewers took to Twitter to voice their annoyance, though it has not been confirmed that Gomez was definitely lip syncing.
We still really enjoyed it though and love the new direction that her performances are going in recently. Not only is social media losing its mind, but back in 2016, an Instagram fan account was created just to photoshop Gomez with blonde hair.

However, her most anticipated accessory - Justin Bieber, who she has reunited with - was missing from the show, with Selena walking the red carpet solo.
The singer delivered an emotional set with Marshmello, the buzzy producer she collaborated with for the new single. "I'd like to see you go through what she has in the past year and perform in front of millions".
Overnight, Selena posted a series of photos on Instagram, giving her fans hints about what her performance at the AMAs would entail and they were VERY haunting. The always brunette star switched things up majorly, and now, fans get even more chances to see what she'll do with the look.
