Actress Jessica Biel reunited with her co-stars Beverley Mitchell and Mackenzie Rosman for an adorable photo op. The former on-screen sisters posted the pic to Instagram on Feb. 9. Mackenzie referenced the show's theme song captioning the snap, "When I see their happy faces smiling back at me, 7th Heaven."

Looks like the girls are still close! Could this mean a 7th Heaven reunion is in the works? The fact that the patriarch of the Camden family, Stephen Collins who played Rev. Eric Camden was involved in a disturbing sex-abuse scandal might make a reunion more complicated.

Brenda Hampton, the series creator, exclusively revealed to Life & Style that she would still want to include Stephen in a reunion.

“I would include him,” she said. “I think all the actors would like to do a reunion show. It would be really fun!”

The news that he was accused of having inappropriate sexual contact with three minors on the show not only shocked fans, but also shocked his co-star and on-screen wife, Catherine Hicks. Catherine said she would only do a reunion if Stephen was not involved.

“I think Catherine was caught off guard and said something off the top of her head,” Brenda added. The scandal, she says, is “so personal, [it’s] none of my business.”

What will become of the once innocent 7th Heaven series? Only time will tell!
