While the cream of the film industry (plus a few L'Oreal models) take to the red carpet in Cannes, over in the USA, The MGM Grand in Las Vegas played host to the Billboard Music Awards 2012, a chance to honour some of the best the music industry has to offer.

In attendance were all the usual suspects, from Taylor Swift (looking gorgeous in red Elie Saab) to Katy Perry (in mermaid-like Blumarine) as well as a few newcomers - most notably Canada's latest pop princess Carly Rae Jepsen.

We were also excited to see Brandy and Monica at the event (we're really, really hopign did an impromptu version of 'The Boy is Mine' after a few glasses of champagne).

The red carpet trend seemed to be all about pale, pastel colours, with lots of white, beige, lilac and cornflower (check out Carrie Underwood looking like a fairy in Oscar de la Renta). Taylor's bold red was one of the only exceptions to the rule, but we love that she ditched the metallic for once.
