Selena Gomez is buzzing after appearing on Wizards Beyond Waverly Place! 

On Friday, Nov. 15, the singer and actress, 32, shared her excitement about reprising her role of Alex Russo on the new spinoff series as she posted photos on Instagram of her filming on set in front of an audience made up of children.

“NOTHING will ever beat making little kids laugh,” Gomez wrote in her caption. “Thank you @disneywizardsseries for making the little girl in me so happy!! Hope you guys watch!! 💜🪄.”

In the first photo shared, the Disney alum smiled as she took a selfie with the audience of kids, who stood waving on a raised platform behind her.

Gomez could then be seen in a following photo smiling alongside her costar David Henrie, who plays her older brother Justin Russo on the show.

Gomez also took a selfie with her young costar Taylor Cora, and other photos included in the post showed Henrie, 35, smiling at the camera while sitting solo in the kitchen set from the show, as well as a final group photo of the cast and crew together on set.

Gomez’s new post comes after her return as Alex in the premiere episode of Wizards Beyond Waverly Place on Disney+ on Oct. 29.

The series serves as a spinoff of the series Wizards of Waverly Place, which aired on Disney Channel from 2007 to 2012.
