From Jennifer Lopez to Britney Spears - see what the stars wore to the Billboard Music Awards

The Cannes film festival wasn't the only red carpet laid out last night - across the pond in Las Vegas the Billboard Music Awards took place, and the dress code couldn't be more (ahem) different.

Stars from the world of music, film and fashion gathered at the MGM Grand last night for the annual awards ceremony.

In the same month that saw barely there sheer creations dominate at the annual Met Gala, it was no surprise that this was a trend that would once again rear its head.

Jennifer Lopez sought to outdo Beyonce's smattering of sequins in her own sheer design - this one by Charbel Zoe couture. Similarly Rita Ora seemed to be barely able to keep her cutaway dress by Fausto Puglisi together.

The night however, in fashion terms belonged firmly to Balmain - who not only dressed many of the stars including Taylor Swift - the French fashion house also chose the evening to announce its upcoming collaboration with H&M, and models Jourdan Dunn and Kendall Jenner were on hand to model looks from the new collection.
