Mariska Hargitay Shakes It Off at Taylor Swift Concert With Daughter in New Footage

Mariska Hargitay and her daughter are showing off their dance moves!

After fans spotted the one and only Olivia Benson walking around the Nissan Stadium in Nashville, TN during Taylor Swift's Eras Tour stop, the 59-year-old took to her Instagram to share a video of her and her daughter, Amaya, enjoying the show.

The footage shows Amaya and her friend watching the show as she dances and sings to "Shake It Off" by the singer. Hargitay then dances her way up to her 12-year-old daughter and her friend as they sway to the hit song.

"'It's like I got this music in my mind Saying it's gonna be alright' ??," Hargitay wrote in the caption before gushing over her longtime friend's performance.

"Thank you magnificent and miraculous @taylorswift for your magic," she wrote. "It’s such a gift to be in your stunning, sparkly, powerful and délicate wonderland. How do you make a stadium filled with with 70,000 people feel like your cozy living room?? You are pure magic! Thank you for exquisite talent, your courage and all your wisdom. Your STAMINA!! and your #SHIMMER #ShakeItOff."

Hargitay and Amaya weren't the only mother-daughter duo in attendance, as the TV star also tagged Reese Witherspoon and her daughter, Ava Phillippe, in her post.

Of course, it didn't take long for fans to celebrate Hargitay's sweet update. "My fave fangirling about my other fave ????????," one fan wrote.

"Those moves, top tier!! ??????????," another user gushed.

"Omg!!! ???? I just know that had to be the most magnificent experience. Taylor is amazing!! ????????????????," a third fan shared.

Hargitay–whose Law and Order: SVU character is Swift’s cat Olivia’s namesake–and the singer's friendship goes way back, as the actress previously joined the singer on stage during her 1989 Tour in Philadelphia, Pennsylvania back in 2015 alongside model Cara Delevingne. For those who missed it, the A-listers notably strutted down the walkway during Swift's song "Style."

The two also appeared in Swift's "Bad Blood" music video in 2014 alongside other celebrities, such as Selena Gomez, Zendaya, Hayley Williams, Karlie Kloss, and more!
