Selena Gomez - Price Tag (Jessie J cover)

Disney teen queen Selena Gomez shows once again what a fan she is of all things British by launching into a brilliant cover of Jessie J's Price Tag. For starters, how amazing does the track sound belted out full volume in a massive venue like this. Pure epic. It's adorable to see Selena do all the dance moves too, you just know she's been sat watching YouTube videos of Jessie to perfect them all.

The Ultra Girls - Girls Will Be Girls

This is quite literally the coolest thing I've seen all week. There's so much great pop flying around at the moment, and The Ultra Girls more than make their mark with this fizzy, full-of-attitude bit of awesome - debut single Girls Will Be Girls!

For starters, there's so many genius lines in the song, 'Trouble with a capital T'... or maybe 'Dangerously, heartbreaking, recklessly, trash-talking, drama-making...' (my favourite bit in the song!) Then there's slinky Pet Shop Boys-esque synth bassline. It's half Saturdays, half Kylie, just aching to soundtrack a night of glitter and glam on the dancefloor. And I haven't even got started on the video yet...

You really can't go wrong with setting your video at an airport can you? There's so much potential for brilliant outfits and other assorted coolness. Colourful? There's more colours here than you can shake a stick at. Lyric-inspired dance moves? The Ultra Girls have got those too as they throw up some 'T' shapes to that aforementioned 'trouble...' line.

And just when you think it's over, a plane flies through space and The Ultra Girls logo appears. It's pop, on an Ultra scale. Amazing.
