Kate Hudson and Kathryn Hahn couldn't be more stoked to team up on the big screen once more.

18 years after they starred together in 2003's How to Lose a Guy in 10 Days, the actresses are both appearing in the upcoming Knives Out sequel, which is currently filming in Greece.

To celebrate, Hudson, 42, shared a fun selfie to Instagram on Tuesday with Hahn, 47, and their respective beaus — Hudson's boyfriend Danny Fujikawa and Hahn's husband Ethan Sandler — cheesing for the camera.

"Reunited baby yeah!!!" Hudson captioned her post. "If we can't get Kathryn Hahn on @instagram then I'll just keep having her take these pics with her selfie face and post them myself!"

She concluded, "Love and missed my bestie ❤️#datenight #feelslikeyesterdayHTLAG."
