"The 100" season 4 won't air until 2017, but the cast and crew are already back to work on the upcoming season of the CW series.

New behind-the-scenes photos from the Vancouver, Canada set of "The 100" season 4 recently surfaced on Twitter, showing the filming site of the dystopian drama.

According to the tweet, the fan stumbled upon the set while hiking in a forest in North Vancouver.

One of the photos showed a sign put up by the production crew, which reads: "100 Films Productions Inc. is currently filming scenes for the TV series 'The 100.' We thank you for your cooperation and apologize for any inconvenience."

Meanwhile, a behind-the-scenes image of executive producer Jason Rothenberg and Marie Avgeropoulos, who plays Octavia in the series, was recently posted online via "The 100" writers' Twitter account.

"@JRothenbergTV and @iamAvgeropoulos enjoying a beautiful(ly rainy) shoot day in Vancouver. #The100," read the caption.

In another tweet, Bob Morley and Eliza Taylor, who play Bellamy and Clarke, respectively, cuddled up for a photo in between takes.

"So nice to see our cast smiling. We must not be rolling. #The100 #THE100SEASON4," reads the caption.

Unfortunately, the photo of Morley and Taylor isn't a sign that "Bellarke" are getting together in "The 100" season 4.

The actress previously dished that Clarke is not yet ready to jump into a new romantic relationship so soon after the death of Lexa (Alycia Debnam-Carey).

"I don't think she's ready to explore new love in her life. When you lose a loved one, you think that that's the end of love for you. That's just how humans react, that's how we grieve. But I definitely don't think that's the end for [Clarke], no matter how much she thinks that she'll never love again, I hope to God she does and I'm sure she will," Taylor told TV Line.

"The 100" season 4 is expected to start airing on The CW this winter or in early 2017.
