Las Vegas got more than its usual quota of glamour last night as the brightest stars of the music world flocked to the MGM Grand to attend the Billboard Music Awards. Former Vegas resident, Celine Dione, felt right at home on the red carpet in her thigh high green leather dress. Followed closely by Britney Spears who has recently announced a three month extension to her Las Vegas residency due to high demand. Spears posed with co-collaborator Iggy Azalea, as the pair begin to enjoy the buzz of their new hit, Pretty Girls.

Ed Sheeran looked relaxed in a simple white shirt and black pants as he headed into the award's ready for his performance of Bloodstream. Sheeran was also up for a number of awards but missed out this year. Fellow performer Mariah Carey kept it simple and classic in all black. 

Jennifer Lopez went sheer in a cut away gown that displayed her toned tummy, in a classically JLo wow-factor ensemble. Rita Ora followed suit in a white cut away gown, embellished by gold stars. Whilst Kendall Jenner went for a power suit look in a black and white padded shoulder jacket dress that wouldn't have looked out of place on her glamorous mother in the 80's) and thigh high suede boots. 

The evening really belonged to Taylor Swift, who chose not to walk the carpet with her new boyfriend, DJ Calvin Harris, and instead was flanked by her band of beauties, Zendaya, actress Hailee Steinfeld, model Lily Aldridge and model Martha Hunt, many of whom star in the cameo laden new video for her hit 'Bad Blood.'
