It’s been a decade, so you might have forgotten, but when Meghan Trainor released her 100% certified bop debut single “All About That Bass” back in 2014, it was a smash. The doo-wop-adjacent song not only hit No. 1 on the Billboard Hot 100, it stayed there for eight consecutive weeks.

Trainor celebrated the 10th anniversary of her break-out smash on Monday (April 29) by dropping in to see Kelly Clarkson on her daytime talk show, where, not for nothing, the host noted that the song was the “best-selling song by a female artist of the previous decade. That’s insane! I feel like you need an Olympic medal for that!”

What better way to fête the firestarter than teaming up with Clarkson for a duet, during which the two singers smiled and bopped their way through the lyrics about having all the right junk in all the right places?

“I see the magazines workin’ that Photoshop/ We know that it ain’t real/ Come on now, make it stop/ If you got beauty, just raise ’em up/ ‘Cause every inch of you is perfect/ From the bottom to the top,” Trainor sang as Clarkson added spot-on ad-libs and the two women fell into perfect harmony on the body positive pre-chorus.

“Yeah, my mama she told me don’t worry about your size/ She says, boys like a little more booty to hold at night/ And no I won’t be no stick-figure, silicone Barbie doll/ So, if that’s what’s you’re into/ Then go ahead and move along,” they harmonized before Clarkson took center stage on the next verse and assured her studio audience that “every inch of you is perfect from the bottom to the top.”

Trainor stuck around to chat as well, with the singer gushing about how in the years since the song has become an anthem for so many fans that she now considers it her “super power.” She also talked about her first tour in seven years and the logistics of traveling with her two young kids, with Clarkson warning that touring with children (and dogs) is going to be a challenge. “Can I give you a tip?,” Clarkson said about the guilt she noted many female musicians have about being on the road with families.

“You feel like you have to wake up with them… don’t do that!” fellow mother of two Clarkson counseled. “Cuz your voice will hate you.”

Trainor recently announced that her sixth studio album, Timeless, is due out on June 14 from Epic Records and dropped the T-Pain-featuring single “Been Like This,” as well as announcing the dates for her Timeless tour, slated to kick off in Cincinnati in September.
