Contrary to popular belief, Justin Bieber had nothing to do with the breakup between Ariana Grande and Big Sean!

The final straw actually came way before the pint-sized pop star even had the inappropriate embrace on stage with Selena Gomez’s ex-boyfriend.

According to ‘TMZ,’ the ‘Bang Bang’ singer was humiliated when her boyfriend released the song ‘Stay Down’ in March and rapped about her … lady parts.

In the song he says, “I got a million-dollar chick with a billion-dollar p–sy/Every time I come, I swear to God I feel rich.”

Although the rapper told ‘Rolling Stone‘ that his girlfriend was “super supportive” of the song and not fazed by it, that clearly wasn’t the case. Ariana was reportedly horrified when it came out — and was even questioned about it by her own grandmother! It was THEN that things started to go downhill.

So if we’re piecing this story together now, the couple weren’t even a couple by the time Ariana and Justin got frisky on stage.

It’s time to find another million dollar chick, Sean.
