The "Misery" singer tweeted a photo of her 7-year-old son, Zuma, with two of his pals on the orange carpet. Stefani's middle child adorably rocked cowboy boots along with a rockstar-worthy denim vest and blue glasses.
We can only assume that the shoe choice was a nod to Shelton, who hosted the Nickelodeon award ceremony. After all, back in November, the 39-year-old country crooner told ET that he wanted Stefani to bring her kids to the show.
Eagle-eyed viewers also spotted Stefani's youngest son, Apollo, in the audience. The No Doubt frontwoman responded to a fan who pointed out the 2-year-old in a screenshot posted to Twitter.
Adorably, Stefani responded that she was FaceTiming with Apollo, and, sure enough, a phone can be seen in front of her little boy. "Wow that is funny!" she tweeted.
@LizbethB12xo ha!!!! That's me on FaceTime from Japan!! Wow that is funny! Gx— Gwen Stefani (@gwenstefani) March 13, 2016
There was no sign of Stefani's eldest son Kingston, 9 -- who spent a day at Disneyland with his mom on Thursday -- during the telecast.
Stefani couldn't attend the KCAs herself, as she was in Tokyo. That's most likely the main reason she resorted to FaceTiming with her youngest, as she was having trouble livestreaming the show from Japan.
Trying to stream 😭🤕🤔😫😖😤😱😰@AllThingsKCAs in Japan ????!!! Gx— Gwen Stefani (@gwenstefani) March 13, 2016
Where r my Japanese fans? Help me stream @AllThingsKCAs gx— Gwen Stefani (@gwenstefani) March 13, 2016
She was never able to find a stream, a fact she shared on Twitter with a big N-O and an angry face emoji.
Monitoring the KCAs via Twitter did appear to help her follow along, however, as Stefani posted a video of her beau getting slimed at the end of the show.
In fact, the 46-year-old singer was so active during the KCAs that a fan couldn't help but point out the social media action.
@gwenstefani can you be this active on twitter everyday? It's giving me LIFE 😍😱💖✨🌻— gx (@DianaPatricia8) March 13, 2016
Nonetheless, Stefani was still bummed that she couldn't catch all the slimy action live alongside her kids and Shelton.
"@AllThingsKCAs omg I love social media = wish I could be there too!" she tweeted at a Kids' Choice Awards Twitter account. "Too many good things at once #Japan #KCA #Misery GX."
One of those good things was that, after a few days of feeling ill, Stefani was finally getting back to her old self. She shared a gorgeous selfie just after the KCAs wrapped up, showing off her signature beauty look of bold red lips and thick black eyeliner, along with the caption, "Hi Japan I'm feeling better."

We're sure Shelton would've loved to have had Stefani in person with him, but he did pretty well hosting the KCAs himself, even with his lady love posted up halfway across the world. Check him out in action in the video below.
