song that I really ever came up with." She later added that "Secondly, just because it's very different from a first single for me. Usually we go with an anthem, guitar-driven song. This is very different... It's just super sassy and it sets up the album nicely," such as "Never Again" (2007) and "My Life Would Suck Without You" (2009). On August 17, 2011, Clarkson revealed that the first single will be "Mr. Know It All," which was set to be released late August. On August 26, 2011, the song leaked online. On August 30, 2011, at 5:30 PM ET, the song was played during a live webcast Clarkson hosted on her official website. The song was available as a digital download from September 5, 2011. Fans who pre-ordered Stronger on Clarkson's official store received the single for free upon its September 5 release. Clarkson recorded an acoustic version of the song for her second extended play iTunes Session in December 2011. In April 2012, a country version, containing re-recorded vocals, of the song, produced by Dann Huff was released.

Critical reception The song has received generally favorable reviews. Upon hearing the single, MTV News commented, "The song is an obvious Clarkson joint: feisty and straightforward, with a strong melody and a sing-along chorus."

Billboard stated that "Clarkson's lyrical message may be one of sass and strength (as fans have come to expect from her), but musically, "Mr. Know It All" is a bit softer; instead of rock-focused energy, the single goes midtempo with touches of piano and subtle strings." VH1 reluctantly admitted their positive review, stating "We don’t have to lie. The mid-tempo ballad isn’t our favorite of her tracks, and we wish her vocals were mixed higher, but we dig it
