Taylor Momsen and Penn Badgley had a mini Gossip Girl reunion over a decade after the show went off air.

If you forgot, Penn, 36, played Dan Humphrey on the hit series. Taylor, 30, brought Dan’s sister Jenny to life for the first four seasons before retuning as a guest for the final season.

The “siblings” got back together again, and it looks like they’ve got something fun on the way!

PodCrushed, the podcast Penn hosts with Nava Kavelin and Sophie Ansari, shared a two pics of Taylor and Penn reuniting at their office on Instagram, presumably to record a new episode of the podcast.

In the first pic, Penn is giving Taylor a noogie while she smiles at the camera. In the second, he’s rocky a smokey eye that wouldn’t be out of place onstage at one of Taylor‘s Pretty Reckless shows!

“A reunion worth waiting for… 👯 but don’t ask us what’s going on in the second photo, we don’t know either,” the podcast teased.

Taylor reposted the photo on her Instagram account but didn’t provide any additional information. We’ll let you know if we hear more!
