David's done it again!
Wow, well we didn't see this one coming! After already scoring a BigTop40 number 1 with the fantastic 'When Love Takes Over', the Guetta has only gone and done it again!
We originally thought there would be a three-way tussle between Black Eyed Peas, Tinchy Stryder and Calvin Harris as they were all hovering at the top of the charts at the start of the show.
But that honour fell to the silent assassin David Guetta as he quickly climbed his way to the top with 'Sexy Chick'.
Other big chart movers included special guest on the show Little Boots who climbed up to number 7 in the chart, from last week's position of 26.
