The full chart will be published tomorrow, but basically the jam sold 411,000 downloads and Spears is now only the second artist ever to have two singles debut at #1 here in the States (the other being Mariah Carey, who entered at the top with "Fantasy," "One Sweet Day" and "Honey").
Now The Weaved One has a fourth chart-topper to her name, while producer-songwriter Max Martin has 10. And this couldn't come soon enough, because if either Bruno Mars' "Grenade" or Katy Perry's "Firework" flip-flopped and was #1 again, I was going to swallow a grenade.
