P.S. Noah Centineo is super jacked now.
The To All the Boys I Loved Before actor shared a new shirtless photo of himself that showed off all of the preparation he's put into his upcoming role as Ken Masters in the upcoming film adaptation of the popular video game series Street Fighter.
Noah wore black sweatpants with pink underwear peeking out as he flexed his arm and flaunted his six-pack abs in the mirror selfie posted to Instagram Aug. 25. But that wasn’t the only transformation he had in store for fans. Also on display was his newly dyed dirty blonde hair that fell to his shoulders, which he had pushed back with a headband.
The 29-year-old cheekily nodded to Street Fighter in the snap's caption, writing, "Road brawler."
Fans didn’t hold back with their reactions took to the comments to react to Noah's transformation reveal, with someone joking, "Did I miss a chapter??" and another person writing, "This is not the Noah Centineo I remember."
A few of Noah's pals weighed in, too, with Rachel Zegler commenting, "NOW HANG ON-" and Lukas Gage writing, "omgggggg."
The Warfare actor's viral pic comes after he opened up about getting healthier and embracing his sobriety journey earlier this year.
“I was so unhappy,” Noah explained on the Chicks in the Office podcast in February. “I was able to pay my bills for the first time. I was completely financially stable and secure. I was working regularly, and I was doing a lot of drugs. Nothing crazy. I was doing drugs a lot. And drinking all the time, every day and I was young.”
“I was 20 years old and I had been doing that for a couple years,” he continued. “So, I had a career that I was proud of. I was making enough money to pay my rent and put a little bit away. You would think I should be super stoked and super happy, and I just wasn’t.”
Noah began his sobriety journey when he was 21 and, while he briefly started drinking while filming 2021's To All The Boys: Always and Forever, now he's sober again.
In fact, working out has been one of the things that has helped him grounded as of late.
“Right now, I’m in one of those phases where I’m just not really doing anything and you just workout,” Noah shared. “And try and connect with yourself and take care of yourself as best as you can. Cause life’s trippy.”
