This may be Maddie Ziegler's fiercest performance yet!

The former Dance Moms star recently attended a master dance class led by Britney Spears' famed music video choreographer, Brian Friedman, at Los Angeles' Millennium Dance Complex, where she absolutely SHUT. IT. DOWN. on the dance floor.

Rocking a sleek ponytail, black-and-white Adidas crop top and matching black pants, the 13-year-old dancing diva worked it out to Ariana Grande's "Into You," pulling out all the sass, flawless technique and fierce facial expressions.

Needless to say, the temperature was definitely rising in that room!

Ziegler, who is a judge on So You Think You Can Dance: Next Generation, is currently gearing up to perform with choreographer Travis Wall on an upcoming episode of the dance competition show.

The two both took to Instagram on Thursday to share a behind-the-scenes pic from rehearsal.

"YAY! so excited for this," Ziegler captioned the snap, which was reposted by the SYTYCD alum. "Catch us on @danceonfox on Monday to see us dance!!!"

Following SYTYCD, Ziegler's going to have her hands full next month as she hits the road for Sia's North American Nostalgic For the Present tour. But if Grande is in need of some additional dancers to join her onstage anytime soon (like Sunday's MTV Video Music Awards), we think Ziegler would fit right in -- the finger snaps, the ponytail, girl's got it all!

ET caught up with Ziegler earlier this month at the Industry Dance Awards, where she adorably gushed over Sia and what it was like when the "Chandelier" singer asked her to join her on tour.
