The Lovatics have spoken! Demi Lovato's 'Really Don't Care' beat out 5 Seconds of Summer's 'Don't Stop,' making it her second Pop Clash win in a row! This week, the powerhouse singer faces off against Austin Mahone's 'All I Ever Need.' Which song should win this week's Pop Clash?

Demi Lovato is all about empowering her fans, and 'Really Don't Care' is the perfect anthem for that! The singer refuses to let the haters bring her down and tells them just that in the song. We especially love that she recruited her Lovatics to appear in the 'Really Don't Care' lyric video! (Just a heads up -- the video is mildly NSFW!)

And speaking of giving back to the fans, Austin Mahone does just that with 'All I Ever Need.' The sweet ballad is enough to make any Mahomie swoon! Austin's smooth vocals shine on this stripped-down slow-burner. The singer croons about loving his special someone despite her flaws. If that isn't adorable enough, the video for 'All I Ever Need' shows Austin interacting with his smitten fans.

Who should win this week's Pop Clash: Demi or Austin? You can vote for your fave song once an hour until the polls close at 3PM ET on June 9.
