Britney Spears has done it again! Thanks to votes from the loyal army of Godney worshippers, Brit's single from 'The Smurfs' sequel, 'Ooh La La' beat Bruno Mars' track 'Treasure' in last week's Pop Clash poll.

That means Spears will go on to another round of competition, and that she's just two wins away from Hall of Fame status!

We're sure Brit's competitor this week is shaking in her boots a little bit, considering she's such a huge fan of Spears herself. Britney's 'Ooh La La' is going up against one of her biggest celeb admirers, Selena Gomez, whose single 'Slow Down' is the latest 'Stars Dance' track to hit the airwaves.

Dr. Luke co-produced Brit's slightly sexy but very sweet smash single 'Ooh La La,' reworking it from an original cut (by Lola Blanc, Ammo and Fransisca Hall) to make it more kid-friendly for 'The Smurfs 2.' The synthpop song contains a strong bubblegum vibe, but also takes on a heavier electro sound, especially during the robotic breakdown. "Ooh my my baby don't be shy / I see that spark flashing in your eye / My heart beats fast 'cause I want it all / So baby come with me and be my ooh la la," Brit sings on the sugary pre-chorus.

Meanwhile, over in Selena Gomez land, the 'Spring Breakers' actress / singer is promoting her second single off of 'Stars Dance,' the all-night party jam 'Slow Down.' Produced by the Cataracs, the masterminds behind hits like Far East Movement's 'Like a G6' and Dev's 'In the Dark,' Gomez described the super-charged club banger as "a really fun song" during an interview about her new LP. She continued, "The beat changes and it’s a vibe where you’re in that moment. The song reflects about slowing that moment down."

So, which song has won you over, and which could you do without? Cast your vote up to once per hour below! This round of Pop Clash closes on July 8 at 3PM EST.

Rules of Pop Clash: The artist and song with the most votes wins, and the winner goes on to face a different challenger the following week. If an artist wins four weeks in a row, they will be retired into the Pop Clash Hall of Fame in order to give others a chance to compete.
