The Blink-182 drummer brought his kids
-- 10-year-old Alabama and 13-year-old Landon -- to the annual awards show, where he was performing "Closer" with the Chainsmokers (a full-circle cameo since Barker's pop punk powerhouse band is name-checked in the song's lyrics!).
ET's Sophie Schillaci caught up with Barker and his adorable kiddos on the red carpet, where the 41-year-old drummer revealed he wouldn't dream of leaving them at home.
"This is my support group," he explained. "Anytime I play an awards show."
Alabama revealed that she and her brother love "supporting him and watching his shows," while Landon shared, "he’s a real good drummer so it's fun to watch."
Also in attendance with Barker was 17-year-old Atiana de la Hoya, the daughter of the drummer's ex, Shanna Moakler, who shared a piece of advice she's received from the musician.
"Just be yourself," she shared. "I feel like we're so like unique as a family, so just own up to it, and be yourself."
Well, no one is better at being himself than Barker, who also spoke about how comfortable his kids have been growing up around the rock star lifestyle.
"All three of them have toured with me since they were like two years old," Barker revealed. "It's kind of all they know and they grew up around it."
"They all played music at a real young age and have been around the industry... they've seen the glamorous side of it, and how much you have to work and rehearse," he added. "I’ve made sure to make them well rounded."
Meanwhile, Barker's kids are developing sizable followings in their own right, on social media at least!
