Derek's live TV name flub

Derek Hough accidentally called contestant Tyler Cameron 'Dylan' while giving feedback during the Season 35 premiere Tuesday night.

“Dylan, you have this, like, Patrick Swayze aura about you, right? You're cool, masculine, just effortless.”

Fans caught it immediately

Viewers took to social media to poke fun at the six-time Mirrorball champion-turned-judge. One fan said the mixup had them 'giggling so hard.'

“Did Derek call Tyler Dylan?!”

The Dylan Efron theory

Some fans theorized Hough confused Cameron with Dylan Efron, who competed last season and came in fourth place as a fan favorite.

“Bro Derek thinks Tyler Cameron is Dylan Efron from last year.”

Tyler and Sharna's tango score

Cameron and partner Sharna Burgess received a 17 out of 30 from the judges for their tango to Lenny Kravitz's 'Are You Gonna Go My Way.'

Bruno Tonioli said he was 'very pleasantly surprised' and noted Cameron has 'so much potential.' Carrie Ann Inaba called his routine 'really solid.'

“I am beyond impressed. That was amazing.”
