“Boyfriend" was one of Justin Bieber's biggest hits. Before he returned to the music scene with last year's "Purpose", the song was his highest-charting single on Billboard Hot 100 as it peaked at No. 2 following its release in 2012. However, it doesn't mean everyone's a fan of the "Believe" cut. One of those people having problem with it is a 11-year-old boy from the United Kingdom who penned a letter in which he called out the Biebs for using the wrong grammar on the song. The boy particularly takes issue with the line, "If I was your boyfriend, I'd never let you go." In his letter, posted on Facebook by his teacher, he pointed out that the specific lyric "used subjunctive mood incorrectly."
