Lady Gaga has always wanted to “just dance,” however she feels.

In the special Christmas episode of Carpool Karaokewhich premiered on Sunday, December 15 and also stars Dua Lipa and Chappell Roan, the 38-year-old pop icon recalled a time when, as a music video extra, she was told to tone things down.

While speaking with Zane Lowe, Gaga took the opportunity to share a clip of her late grandmother singing the 1979 AC/DC classic “Highway to Hell.”

Both the Apple Music 1 host, 51, and the “Disease” singer laughed at the clip of Gaga’s grandma shouting the lyrics from a chair in her living room.

“Get it, Grandma!” Gaga remarked.

As the “Alejandro” musician emotionally spoke about the lessons she learned from her grandma, Lowe exited the vehicle to retrieve Gaga’s Christmas present – AC/DC singer Brian Johnson.

The two then performed a duet of “Highway to Hell” together, while Johnson, 47, was overwhelmed by Gaga’s impressive vocals.

After the duo rocked out some more, Gaga recalled being an extra in an AC/DC music video in 2000.

“Would you like to hear something funny? I was in the video for ‘Stiff Upper Lip,'” she told Johnson. “I was 17 and I was a background extra.”

At the time, Gaga said she was “headbanging,” which didn’t go over particularly well.

“I was headbanging and they were like ‘hmmm.’ No headbanging, we want it to be modern. And I thought, ‘No, there’s only one thing I can do,'” she recalls.

During the episode, Gaga also sang her 2008 holiday single “Christmas Tree,” whose suggestive lyrics confused Lowe, including “Under the mistletoe, everyone knows we’re going to get naked” and “My Christmas tree is delicious.”

“Zane, my husband. Listen, I need a favor, okay? I have three friends, they just need a ride,” he told Lowe during a phone conversation at the start of the special.
