Take a look and listen to the top 25 pop songs of 2009 thanks to this incredible mash-up by DJ Earworm called ‘The United States Of Pop 2009 (Blame It On The Pop)’.

I can’t stop laughing at Kelly Clarkson’s Halloween costume…hilarious! Clarskon dressed up as Stewie from Family Guy.

Clarkson had a little surprise for fans while she performed her current single ‘Already Gone’. After all of the controversy surrounding the song and it’s similarities to Beyoncé’s ‘Halo’, Clarkson belted out a little ‘Halo’ towards the end of the song. Imagine if Clarkson had recorded and released ‘Halo’…it would have been even more amazing!

Seems like everyone’s doing a cover of the Kings Of Leon hit ‘Use Somebody’. Kelly Clarkson, Paramore, and Brooke White have all recently covered the song and now, Justin Timberlake can be added to the list.

At a recent show in Las Vegas, Timberlake performed a mash up of his hit ‘Cry Me A River’ and Kings Of Leon’s ‘Use Somebody’. It’s seems appropriate that Justin would cover the band at some point since it’s been reported that Timberlake will be working on the bands remix album.
