Lady Gaga channeled her inner goth girl to join in on a viral TikTok trend this week.

The "Bad Romance singer posted a video of herself on Thursday doing the "Wednesday" dance -- the routine popularized by the titular character in Netflix's "Wednesday" -- to one of her own songs.

"BLOODY WEDNESDAY," Gaga captioned the video, which showed her putting on makeup and getting dressed in her best Wednesday Addams cosplay before busting a move to "Bloody Mary," a deep cut off her 2011 album "Born This Way."

The viral trend, inspired by "Wednesday" star Jenna Ortega's quirky moves on the hit Netflix series, has been blowing up TikTok the past few weeks -- and this isn't the first time Gaga has taken notice.

"I see you doing my dance moves to @LadyGaga's Bloody Mary. I understand she is followed by little monsters. I approve," the show's official Twitter account tweeted on Dec. 1.

This garnered a response from Gaga herself, who replied, "Slay Wednesday! 💋 You're welcome at Haus of Gaga anytime (and bring Thing with you, we love paws around here 😉)."

While the social media trend has people dancing to Gaga's song "Bloody Mary," Ortega's Wednesday actually grooves to "Goo Goo Muck" by The Cramps in the show.
