The star wore a black Alexander McQueen shirt with a gold harness with black pants, completing the look with a pair of black trainers.

Taking to Twitter, Jacob shared a photo of himself at the 2016 Oscars where he sweetly gave the camera a thumbs up, next to the snap of himself at the premiere last week.

"Good god I'm old," another quipped.

"The kid is growing up only means I'm getting old," a third added with a crying emoji.

One user also pointed out that Jacob shared a striking resemblance to singer Shawn Mendes and actor Timothee Chalamet.

"Wow, what a glow up! Crazy how time has gone by so fast!" someone else wrote.

On Instagram, the comments continued, with Michael B Jordan writing, "Young man."

"Oh my goodness, all grown up!" another said.

"Sir you are handsome," one fan added, while someone else wrote, "Stunning bro!"

Jacob has been doing a lot of work as a voice actor lately, which could be why fans haven't seen much of him.

The actor will be appearing in the new live-action version of The Little Mermaid as the voice of Flounder and also worked on Luca as the title character.

According to IMDb, Jacob has quite a few projects that are set for release in the near future, with eight projects in different phases of completion.
