13 Going on 30 fans, we bet you didn't expect to see this reunion happening!

On March 31, Jennifer Garner (who portrayed Jenna Rink) shocked fans when she posted a surprise get-together with someone folks didn't expect. Posting on Instagram a series of images, she shared she was filming The Last Thing He Told Me season 2 in Paris. And if that wasn't enough, she reunited with her former co-star Judy Greer, who played Lucy "Tom Tom" Wyman in the 2004 comedy film and is a new cast member for the Apple TV+ series.

"JG & JG take Paris. ♥️ #TheLastThingHeToldMe," Jennifer simply wrote alongside videos and images of her and Judy's time together in the caption.

While many were excited to see Jennifer and Judy hanging out on the streets of Paris, some fans noticed one important person missing from this reunion. As a result, they took to the comments to ask where Mark Ruffalo (who played Matty Flamhaff in 13 Going on 30) was for this reunion.

"Where is Matty?! 😍😍😍," one person begged in the comments, referencing Mark's character in the movie. "Where are you Matty? @markruffalo," another inquired. "He was the one taking the pics," a different follower joked about Mark's potential whereabouts.

While it was clear Jennifer and Judy were in Europe to film their mutual TV project, we love how this brought so much joy to 13 Going on 30 fans worldwide! And though Mark wasn't with them on this epic acting adventure, fans may remember the trio did reunite (albeit virtually) back in April 2024 to celebrate the 20th anniversary of their joint project hitting movie theaters.

"#13GoingOn30," she wrote on Instagram at the time. "Twenty years. We are three Boomers braving zoom—because we want to thank you. 👴👵👵 To every person who has loved this movie along with us: Thank You. We see you, we appreciate you and we love you back. Forever thirty, flirty and thriving! 💕."

Well, here's to the next catch-up!
