KATYPERRYADIDAS2012.jpgWho knew tracksuits could be so sexy?! Unlike the pink horrorEmma Watson sported for her new role recently, Katy Perry has been busy showing us all how to look ridiculously hot in a pink Adidas number for the global brands campaign "Adidas Is All In". The campaign (which is the biggest the sports brand has ever executed) features Katy a number of times, and funnily enough, the 26-year-old singer is the freshest talent in a long line of 'celebrity' brand ambassadors. Although many people have questioned why Katy is used alongside several notable athletes such as footballer David Beckham and tennis player Caroline Wozniacki, Adidas obviously stand by their decision, and quite rightly too - Katy looks amazingly toned and happy throughout the adverts, including the newest edition entitled "We All Run".

As well as following the gorgeous Beckham in a run along the Thames in London, the ad shows snippets of our favourite quirky singer with her blue bob (the video was shot back in January, not long after her split with comedian Russell Brand) running down a boardwalk with her friends in California. Sporting vibrant purple, red and peach attire, Katy looks sleek and not at all red faced as she waves at Adidas Originals designer Jeremy Scott who cycles past her on a bike. I definitely don't look that good when I exercise! With the 90's trend fresh in our minds and of course, that little event called the London 2012 Olympic and Paralympic Games, it's no wonder that all of Katy's Adidas videos are also doing the rounds - including the women's special Adidas All In, which is my personal favourite.

Do either of the videos get you in the mood for the gym or make you want to celebrate London 2012? Let us know in the comments below!
