One Disney darling is facing off against another in this week's Pop Clash! Last week, Britney Spears triumphed over A Great Big World and this week she's up against Demi Lovato. Brit's 'Perfume' has already won three rounds of Pop Clash, but can she take down Demi's 'Neon Lights'? It's up to you to decide!

Britney goes into power ballad mode with 'Perfume.' The emotional song shows the singer's vulnerable side and makes us like her even more. In the lyrics, Brit admits she's paranoid her boo is unfaithful, which is sad but very relatable. 'Perfume' is proving to be the perfect followup to the success of 'Work Bitch.'

Demi's 'Neon Lights' is an EDM, pump up anthem. The songstress asserts herself as ultra-confident, promising a guy he'll be coming home with her tonight. Sizzling! The dancey track lets Demi do what Demi does best: Work her vocals.

Whose song do you like better: Britney's or Demi's? You can votes once an hour until the polls close at 3PM ET on Dec. 2.
