‘The Flash' season 3 spoilers: Grant Gustin shares photos as Barry Allen from different timelines

"The Flash" season 3 lead star Grant Gustin recently shared some photos from the set of the hit The CW series.

In the first photo, Gustin could be seen with a mustache. He also posed with his co-star Carlos Valdes.

There are rumors that some scenes of Gustin in "The Flash" season 3 will feature a much older version of his character Barry Allen.

After all, in the finale episode for season 2, Barry decided to alter the timeline to ensure that his mom Nora wouldn't be killed off.

"Los made the same face this whole shoot. My love is just so real," he captioned the photo.

Another photo once again featured the actor with his mustache. It's quite obvious that he also looks so much older in the snap.

"Everyone's telling me to shave - and I'm like..." he wrote.

Another photo showed Gustin with a clean-shaven face. By the look of it, the snap confirmed how Barry would look like when he's portraying a much younger version of himself.

"Look who's back. Baby faced Barry. #Day1 #TheFlashSeason3," he wrote.

Meanwhile, Gustin isn't the only cast member who has been sharing photos from the set of "The Flash" season 3.

First day back snap.
