For the third week in a row, Demi Lovato locked in the Pop Clash title! Last round, she went head-to-head with Austin Mahone and walked away with more than 75% of the votes! This week, Demi's 'Really Don't Care' is up against Nicki Minaj's 'Pills N Potions.' Which song should win Pop Clash?

Demi's 'Really Don't Care' is the perfect anthem for Lovatics! It shows off Demi's incredible voice, while also emphasizing the message that she's not about to let her haters get her down. The upbeat track is chant-ready, with the ultra catchy "Really don't care!" in the chorus.

From the thumping intro beats to Nicki's crystal clear voice, 'Pills N Potions' is infectious. The slow-burning track is a different side of the singer -- and we love it. Of course, no Nicki song would be complete without her rapid-fire raps and 'Pills N Potions' is no exception. The dreamy melodies and vulnerable lyrics make this song a total win for us.

Which song should win this week's Pop Clash? You can vote for Demi or Nicki once an hour until the polls close at 3PM ET on June 16. (Head's up, both videos are slightly NSFW.)
