Britney Spears vs. Ariana Grande – Pop Clash

It's a battle of the pop princesses! Last week, Britney Spears dethroned previous champ Justin Bieber to take the Pop Clash title! Brit's latest single, 'Perfume,' is the perfect power ballad to follow the success of 'Work Bitch.' Is it enough to hold off this week's challenger, Ariana Grande's 'Right There'?

Britney tugs on our heartstrings with 'Perfume.' We can all relate to the feeling of not being able to trust a significant other, but Britney drives the point home as she croons about imagining her boo is cheating. The singer has had her fair share of heartbreak (Britney + Justin Forever!), and she channels a lot of emotion into this "Is he/ isn't he" track.

Britney maybe mourning a relationship on the rocks, but Ariana is celebrating the start of something new. Her sugary-sweet track, 'Right There,' is about finding that special someone and never letting him go. Ariana promises that if he never changes, she'll never leave. Ahh, to be young and in love.
