Could Little J and Eric be returning for a family reunion on the Gossip Girl series finale? It sure looks that way!

Kelly Rutherford tweeted a photo of Taylor Momsen and Revenge's Connor Paolo from the set Tuesday. "My kids are grown up!!" she wrote. This would seem to indicate the duo will be popping up, especially considering the CW series is currently filming its series finale. Reps for the show didn't immediately respond to's request for comment.

Katie Cassidy returning to Gossip Girl

Jenny Humphrey and Eric van der Woodsen last appeared in Season 4, but the show has since suggested that both characters have been abroad.

If the actors do return, they won't be the only familiar faces coming back: It was announced last week that Katie Cassidy will reprise her role as Juliet Sharp. Who else would you like to see pop up?

Gossip Girl's series finale will air Dec. 10 at 9/8c on The CW.
