Britney Spears is the winner of our latest Pop Clash poll! After a heated battle with Rihanna, who was in the running with her new, David Guetta-featured single 'Right Now,' Spears has officially taken the win. Congratulations to Brit and her fans! This means 'Ooh La La,' from the upcoming 'Smurfs' sequel, will go on to face a different competitor in our reader-voted song battle.

This week, Britney's bubbly new jam 'Ooh La La' is squaring off against Bruno Mars' funky, feel-good single 'Treasure.' After listening to both tracks, which do you like best?

After having a huge hit with, Spears is back doing her solo thing on 'Ooh La La.' The effervescent, lighthearted pop track finds Brit praising a man for his stellar personality, not for his cash flow or good looks. Spears busts out that wonderful nasally voice, singing, "You don't have to roll like a millionaire / Baby I would go with you anywhere / We don't need no gold, we'll be shining anyway, we'll see." The pre-chorus breakdown features some heavier dance beats, before Brit gets all sweet again, asking for a guy to "come with me and be my ooh la la."

Bruno Mars' dance-y single 'Treasure' is also about love, except he pulls a 'Just the Way You Are' as he tells his doubtful lady how special she really is. He gets soulful on this funky, disco-inspired 'Unorthodox Jukebox' track. The intro is very Bruno, as the digitized line "baby squirrel, you a sexy motherf-----" gives way to a huge horn section and Mars' smooth vocals, as he sings, "Give me your, give me your, give me your attention baby / I got to tell you a little something about yourself / You're wonderful, flawless, ooh you're a sexy lady / But you walk around here like you wanna be someone else."

So, which of these tracks is your favorite? Vote for Britney Spears' 'Ooh La La' or Bruno Mars' 'Treasure' below! The poll is set to close on Monday, July 1, at 3PM EST, and you can vote once per hour up until then.
