Watch HAIM Perform Britney Spears' 'Oops' Dance Front Row Of Her Vegas Show

In case you didn't know, HAIM loves themselves some Britney Spears and the alt act put their stan cards on full display when they attended one of the pop titan's last "Piece of Me" Las Vegas residency shows on Tuesday (December 19) by going full-out with the iconic "Oops...I Did It Again" choreography.

Just a day after the concert event, Este, Alana and Danielle Haim took to social media to share the front row footage of them recreating Spears' 2000 dance from the Nigel Dick-directed visual and they absolutely nail every single move. "drunk moms at a bar mitzvah," the trio captioned the footage, which has solidified their fandom for the "Slumber Party" singer. 

HAIM are long-time Spears fans, who previously shared their love for the singer's catalog during a guest host radio stint, where they played a string of Britney cuts and gushed about the singer. Earlier this year, they also participated in FADER's 10-year anniversary piece on the pop titan's critical acclaimed LP, Blackout, which was released back in October 2007. 

"I think it's no secret that we love Britney Spears. We did a whole radio show dedicated to her and we played 'Break the Ice,' which might be my favorite Britney song," Danielle revealed. "It feels like Britney really did what she wanted with this record, which is so refreshing for that time coming off a bunch of records where she was prim and proper. This record came out and it felt like she was being herself and not letting anyone tell her what to do."
