‘Two and a Half Men’ star Angus T. Jones unrecognizable on barefoot walk

They grow up so fast.

Angus T. Jones was spotted Sunday looking much older than his “Two and a Half Men” days, in his first public sighting in nearly a year.

In new photos obtained by The Post, the now-bearded 29-year-old kept it casual in an oversized grey T-shirt and dark grey shorts while he walked barefoot around his Los Angeles neighborhood.

He paired his Dahmer-style glasses with a backward red baseball cap that covered his nearly-balding head.

The Post has contacted a rep for Jones for comment.

Jones rose to fame as Jake Harper in the famed CBS sitcom, alongside Charlie Sheen and Jon Cryer.

He officially announced his departure in 2014 — though he did appear in the 2015 series finale — after rediscovering his Christian faith and dubbing the series “filth” in an impassioned 2012 rant.

“If you watch ‘Two and a Half Men,’ please stop watching ‘Two and a Half Men,’” he preached in a YouTube video posted by the Christian group Forerunner Chronicles.

“I’m on ‘Two and a Half Men,’ and I don’t want to be on it. Please stop watching it and filling your head with filth. People say it’s just entertainment…” he continued.

Jones added: “Do some research on the effects of television and your brain, and I promise you you’ll have a decision to make when it comes to television, especially with what you watch.”

The former child star became somewhat of a recluse after his spiritual journey and has rarely been spotted in public.

Sheen was fired from the show in March 2011 due to his bizarre media antics. Ashton Kutcher replaced him for four seasons, until the series finally ended in 2015.

Jones later issued an apology about his “Men” remarks, but claimed he didn’t regret stepping away from the show because he was “really, really excited about” going to college.

“I apologize if my remarks reflect me showing indifference to and disrespect of my colleagues and a lack of appreciation of the extraordinary opportunity of which I have been blessed. I never intended that,” Jones said in a November 2012 statement.

Jones told People in 2016 that enrolling at the University of Colorado at Boulder allowed him to live “a normal existence.”

“I wasn’t the center of everyone’s attention, and that was nice,” he said.
