Selena Gomez Sings Britney Spears Classic In A Throwback Video; Fans React

Selena Gomez shared a hilarious throwback video Tuesday on social media that was filmed even before her Disney days.

In the video posted on Instagram on Tuesday, the 28-year-old actress-singer seems to enjoy herself as she sings "Don't Go Knockin' on My Door" by Britney Spears.

The video has a purple and white animated space-themed background. Gomez can be seen performing the song with transparent blue sunglasses and at the end of the video, she removes them in style. "The hustle was real," Gomez captioned the video.

Celebs and fans couldn't hold back their excitement as they shared their reaction to the incredibly confident video by baby Gomez.

Stand-up comedian Amy Schumer commented, "Stop it!," while Australian singer Celina Sharma noted, "mood."

"Killer Camera Monsters" star Sarati commented, "This is gold." Actor Hunter Reese Peña noted this was how he used to add effects in the background back then. "The effects on my first music video be like," he wrote.

One of the users noted, "Talented from a young age so cute" while another user wrote, "This made my morning."

On the same day, Spears posted a single picture of herself three times in a row on Instagram. While fans appreciated the first photo, they started wondering why the pop star posted the same photo more than once.

One of the fans commented on Spears' photo, "bestie you posted this 3 times in a row?!" Another user wrote, "So many screen shots taken of this pic that now you can see the pixels."

Some fans wondered what the singer meant by "ROSE."

Gomez will next do the voice-over for the fourth installment of "Hotel Transylvania." The animated movie is slated to release on July 23.

She will also star in the comedy series "Only Murders In the Building," which will release on Aug. 31. The Hulu series also stars Aaron Dominguez, Steve Martin and Martin Short.

Spears released her documentary, "Framing Britney Spears," in February.
