Beyoncé is one of the most prolific artists of all time. Not just to Kanye either… it’s pretty much a universally known fact. She and her husband make up two of music’s heavy hitters as Jay-Z has had just as big of an impact in the rap sector of the industry. It’s also a well-known matter that Queen Bey doesn’t mind getting her hands dirty and tousling up her hair every once in a while. This is the woman that dropped Lemonade after all. The identity of “Becky with the good hair” is still up in the air and the mystery of “who bit Beyoncé” is still being discussed but Bey may have fans wondering who exactly she’s dissing this time around after this.

During a recent concert with her husband, the “Halo” singer switched up her lyrics a little bit while performing “Resentment.” The original lyrics are pretty harsh as the B’Day track goes, “Like I couldn’t do it for you like your mistress could.” The leader of the Beyhive went at it a little differently as she seemingly called someone out, changing the lyrics to: “Like I couldn’t do it for you, like that desperate, mediocre, wack b-tch could.” Yikes.

She also included a line where she compares her success with the unnamed lady, saying, “she ain’t even half of me, and that b-tch will never be.” Could she be taking further jabs at the undetermined Becky here? If not, who could she be referring to? Peep the clip below.
