Kelly Clarkson and Meghan Trainor Sing Killer ‘All About That Bass’ Duet

Kelly Clarkson and Meghan Trainor prove that they're "All About That Bass" -- no treble -- in a striking duet celebrating Trainor's 10th anniversary of her hit song.

During the Kellyoke segment on Clarkson's talk show on Monday (April 29), the two singers teamed up to perform a beautiful harmony of Trainor's 2014 track. As Trainor, 30, and Clarkson, 42, sang the song's original body-positive lyrics, the two went back and forth, taking turns showcasing their vocal chops.

During her Monday appearance on The Kelly Clarkson Show, Trainor opened up to the host about how in the last decade since "All About That Bass," the song has become an anthem for her "Megatronz." The mother of two now considers it her “superpower.” Trainor shares sons Riley, 3, and 9-month-old Barry with husband Daryl Sabara. She also talked about her first tour in seven years and how traveling with her young children would be a challenge.

With two children of her own, Clarkson offered the Grammy-winning artist some words of advice. "You feel like you have to wake up with them… don’t do that!” Clarkson counseled. “'Cause your voice will hate you.”

Trainor recently announced that her sixth studio album, Timeless, is set to release on June 14th. Ahead of the release, she dropped the single "Been Like This," featuring T-Pain. T-Pain revealed he spent quite a bit of time trying to make a collaboration with Trainor come to fruition. The 39-year-old singer and rapper said he’s worked with Meghan’s husband and manager “for MONTHS trying to surprise her for her birthday" (she turned 30 in December). "She’s been a fan of mine for a long time, and the feeling is definitely mutual.”

While on The Kelly Clarkson Show, Trainor gushed about T-Pain, saying she feels like she's been working her entire career "Just to work with T-Pain."

Her accompanying tour is slated to kick off in Cincinnati, Ohio in September, finishing off in Inglewood, California on October 19th. Natasha Bedingfield is set to be her opener for her tour in select cities. Paul Russell, Chris Olsen, and Ryan Trainor (her younger brother) are also joining Trainor on her tour. Kicking off on September 4 in Cincinnati, Ohio, the tour is a month and a half long, concluding in Inglewood, California, on October 19th.

It seems that Kelly Clarkson's Kellyoke performances get better and better with each passing year. The daily segment on her talk show features the powerhouse singer playing a live rendition of popular songs spanning all genres and decades.

From Christina Aguilera to Chris Stapleton to Måneskin, you don’t know what song she will put her own spin on next. Since we started doing this list ranking her best Kellyoke performances back in 2022, some of our favorite covers that year include a Jennifer Lopez ballad rendition of "Waiting For Tonight," Billie Eilish's "Happier Than Ever," Anita Bell's disco track "Ring My Bell," Adele's "Rumor Has It," and even Radiohead's "Exit Music (For A Film)."

In 2023, Clarkson kept fans on her toes with even more breathtaking covers. Our picks of the standout Kellyoke's from 2023 include Taylor Swift's version of "Better Man," Destiny's Child's 2001 hit song, "Survivor," Cher's "Strong Enough," Daniel Bedingfield's pop anthem "Gotta Get Through This," and Chris Stapleton's "Tennessee Whiskey."

Clarkson previously released an album of six of her covers from 2022 after “singing over 500” on The Kelly Clarkson Show, which she said was “near-impossible” to choose. The Kellyoke album was released in June of 2022 and features the following songs:

Her latest album was 2022's Chemistry. When announcing her 10th studio album ahead of its release, the singer-songwriter said she didn’t want “everybody” to think that her emotions could just be simplified as angry or sad. She explained in a video shared on X (formerly Twitter), “This album is definitely the arc of an entire relationship, and a whole relationship shouldn’t be just brought down to one thing. So there’s the good, the bad, the ugly thing kinda going on in it."

With hundreds of Kellyoke performances under her belt and the number growing by the day, we conducted a list of her best performances of 2024 so far.

Take a look below at Kelly Clarkson's best Kellyoke performances of 2024:

Kelly Clarkson's March 19 Kellyoke cover of Katy Perry's "Wide Awake" was so good, Perry herself commented on the social post: "ok dang I can never sing that again." One fan hilariously offered Perry their condolences: “so sorry my sister Katy. what’s done is done.” Clarkson’s covers are so good, they sometimes sound better than the original, and this one is no exception. Clarkson tackled Perry's 2012 hit track in the style of a ballad, with a piano accompaniment.

Taking things to a sultry level, Kelly's cover of Marky Marky's 1991 hit, "Good Vibrations," gave us some serious chills! Though we weren't even born yet when the original dropped, we remember hearing this on the radio growing up in the '90s. Kelly's rendition breathes a completely new life into the hit. If we weren't familiar with the original, we wouldn't have even known it was a cover the way she sang it.

Kelly retained the edginess and rawness of Aguilera's original version of 2002's "Fighter," even with the electric guitars. Clarkson changed up how she sang the song's bridge and let her vocal chops loose, garnering applause and cheers from the crowds. This moment confirmed that she could go toe-to-toe with Aguilera's range.

This isn't Kelly's first Miley cover, and we're sure it won't be her last. During this Kellyoke segment, the host chose Miley's track from 2023's Endless Summer Vacation. The song, which is all about the naivety and mistakes we made when we were younger, was given new life the way Kelly belted out the track.

With no studio audience while taping this performance, Clarkson hyped the song up a nonexistent crowd. Crowd or not, Clarkson clearly had a ball covering this Estefan hit from 1989. The brass section and her backup singers bring so much depth to Kelly's fun cover, where she does, in fact, ask the nonexistent crowd to join her and get on their feet.

In another dance '80s throwback, Kelly tackles Chaka Khan's iconic 1983 hit, "Ain't Nobody." During half of the performance, Kelly sings the song pretty much like the original. After a minute though, she lets her voice ring high as she sings the chorus for the third time and does her personal spin on it and belts it out.

Taking on Billie Eilish's Grammy-winning smash from the Barbie soundtrack, Kelly looked stunning in a red dress while singing the melancholy track. With a piano accompaniment, Clarkson retained the sadness in her rendition, then changed the mood of it completely when she belts out "someday." We're sure Billie can appreciate the change-up, as we did, and hope Kelly does more covers of her songs in the future.
