The 22-year-old singer-songwriter posted a video of him saying, "I'm hosting the Kids' Choice Awards."
At the beginning of the video, Jonas was about to get slimmed as he stood while striking a cool pose.
The 'When You Look Me in the Eyes' crooner sported an all-black outfit including sunglasses, black tee, leather jacket and pants. He captioned it, "3.28.15 #KCA NickelodeonTV."
On Tuesday, Jonas teased his fans about his upcoming Kids' Choice Awards hosting gig.
"What do me and Cameron Diaz have in common... ? What do me and Will Smith have in common? Have any ideas what me and the last couple people I mentioned have in common? How bout Jack Black and I?" he tweeted.
