Mark Ruffalo shared a sweet selfie with his "13 Going on 30" costar Jennifer Garner after the two reunited in Canada.

"Reconnecting with an old pal. Anyone know where we can get Razzles in Canada?" Ruffalo captioned the photo of the two of them.

The "Avengers" star was referencing the '80s candy that features prominently in the 2004 rom-com.

Garner also shared the selfie to her Instagram, and included another wink to the movie's plot in her caption.

"Wishing dust worked! And I got a perfect day with my old pal," Garner wrote.

Fans were loving Ruffalo and Garner's reunion on social media, with many sharing clips and photos from "13 Going on 30."

"This is a canon update of their characters for me," one fan wrote.

Ruffalo and Garner reportedly reunited on the set of sci-fi film "The Adam Project" (which is currently shooting in Canada), nearly 17 years after "13 Going on 30" was released.

The rom-com focuses on Garner's character Jenna Rink, a nerdy teenager who wakes up the day after her failed 13th birthday party as a successful adult, thanks to some magic "wishing dust."

Throughout the film, Jenna is forced to confront the ways in which adult life and popularity have changed her, and also reexamines her relationship with her childhood best friend, Matty (played by Ruffalo).
