It's a rare sighting of Scully and Mulder together!
Gillian Anderson, who played agent Dana Scully on the "The X-Files" snapped a selfie with her David Duchovny, who played agent Fox Mulder on the hit show. Not only that, but she also introduced him to her adorable dog.
"Stella made a new friend today. #davidduchovny," Anderson wrote on Instagram.
Fans were thrilled to see the two stars back together again.
"I've just died a thousand deaths from one photo!!" one person wrote, along with two hearts and two crying emoji.
"THANK YOU NOW I'M CRYING," another fan added.
It seemed to be a common reaction among the diehard fans of the show.
"The way you knew this would break the internet," someone else commented.
The popular television series, which followed FBI agents Scully and Mulder as they investigated paranormal cases, ran from 1993 to 2002. Anderson, 52, and Duchovny, 60, also starred in two spin-off movies in 1998 and 2008.
The series was revived for two more seasons, from 2016 to 2018. When Scully was written off the final season of the show, Anderson confirmed that would be the last fans ever see of the special agent.
"It’s time for me to hang up Scully’s hat. It just is,” Anderson said in 2018, according to The Hollywood Reporter. "I’m finished and that’s the end of that."
At the time, Anderson added she was looking forward to taking on new roles.
"There’s lots of things that I want to do in my life and in my career and it’s been an extraordinary opportunity and extraordinary character and I am hugely grateful," she said.
Anderson most recently played former British Prime Minister Margaret Thatcher on "The Crown," and earned praise for her portrayal of the Iron Lady. In February, she took home the Golden Globe Award for best supporting actress in a series, mini-series or television film.
It's unclear whether the actors were together for an undisclosed work reason or if they were simply in the same area and overdue for a catch-up. Last August, FOX announced an animated spinoff called "The X-Files: Albuquerque."
While both actors aren't at least publicly attached to the show, "The X-Files" creator Chris Carter will executive produce the series, according to Variety.
