"Smash" filming has ended for the principal cast for Season 2 ... and maybe for good.

Several cast members including Megan Hilty, Debra Messing and Katharine McPhee took to Twitter to share photos and thoughts about the end of Season 2.

While no official word has come down the pipeline, this looks like it'll be the last season for "Smash." The show has struggled in the Nielsen ratings since its sophomore debut in February. Its most recent outing was adjusted up to 2.7 million viewers and a 0.8 rating in the 18-49 demographic, down dramatically compared to its Season 1 numbers.

In February, Hilty told HuffPost TV that she tries not to worry about ratings. "Listen, as an actress I realized a long time ago there are a lot of things out of my control," she said. "Those are the things I can't let affect me because what can I do? All I can do is show up and do the best work that I can and the rest is in everybody else's hands."
