Watch Noah Centineo React to a Clip of His First Kiss on 'Late Late Show' Appearance

Fans can't decide what's funnier, the kiss or the actor's reaction.

Noah Centineo lived every actor's worst nightmare this week as he was forced to re-watch a throwback clip of his first on-screen kiss. 

The Perfect Date actor, 26, appeared as a guest on The Late Late Show with James Corden on Wednesday, Dec. 7, when the late-night talk show host said he had "tracked down" footage of Centineo's embarrassing coming-of-age moment. 

As Corden, 44, introduced the clip, Centineo tried yelling, "No! No!" while the audience roared with laughter and excitement as the footage began rolling. 

The on-screen smooch was part of the actor's first-ever movie, The Gold Retrievers (2009). In the magnetic clip, Centineo rocked a shaggy Justin Bieber-like haircut while his co-star Courtney Biggs gave him a quick peck on the lips. 

After Corden refreshed his memory of the moment, Centineo burst out laughing while cringing over the face he made in the movie, as his character looked utterly stunned to have received a kiss.

Once the laughter finally simmered down, Corden requested a still of Centineo's hair to be put back on the screen as he told the Fosters alum that he looked like an "Early Bieber" or an "Early One Direction" member. 

"It's actually crazy that you say that I used to get recognized as Justin Bieber all the time," Centineo then told the talk show host, who joked, "yeah, same." 

But the To All the Boys I've Loved Before star explained more, giving an example of when he was mistaken for Bieber while on a cruise.

"I remember I was on a cruise, and I had like an army of people like chasing after me thinking I was Justin Bieber," he recalled. "I just ran as fast as I could, and it wasn't until the second day of the cruise that they realized I was a fraud." 

After the interview, both the Late Late Show and Centineo shared the video to Instagram in a joint post that was captioned, "This clip of @ncentineo’s first kiss is giving off big Bieber vibes 💇‍♂️" 

But Centineo's fans in the comments couldn't get over the hilarious first kiss, with one person writing, "Idk what’s funnier, the kiss itself or his reaction 😂"

"Noah’s reaction to his young-self acting is fr [for real] the best thing in the world😭🫶🏼" another wrote.
