If fans feel like they haven't seen Jesse McCartney in a while, that might be because the actor spends a lot of time in the recording booth, working as a voice actor. It's a career path he's been on since the mid-2000s when he voiced Theodore in the live-action "Alvin and the Chipmunks" films. He lent his voice to "Horton Hears a Who," played a Hardy brother in a "Hardy Boys" video game, and even appeared as a character called Terence in multiple animated "Tinker Bell" movies.

Perhaps most famously, McCartney voiced Dick Grayson on "Young Justice," a superhero cartoon, from 2010 to 2022. When the series premiered, he told CBR that he took the responsibility of playing such an iconic character seriously. "I used to watch these shows when I was younger and now to be a part of it is sort of overwhelming," he said.

"Voiceovers are like, I think, a part of my career nobody knows about," McCartney told "The Zach Sang Show" (via YouTube). He added that he rolls out of bed, makes his coffee, and goes to the recording studio in his pajamas, noting that voice acting gigs are "a good way to make dough." Having that income is important, McCartney said, because it allows him to do other things. "I supplement a lot of, like, my music, and being in the music industry, and trying to make music, with stuff like that. ... Those are my bread and butter."
