London, Nov 10 (ANI): It looked like American divas Beyonce and Mariah Carey were competing to be the last arrivals at the World Music Awards in Monte Carlo.

Beyonce, who had skipped the red carpet with her late arrival, had to give up arriving any later as she had the opening slot on the show, which was already delayed by an hour.

The Crazy in Love singer was dressed in sexy black leather trousers, and she made sure that the waiting was well worth it as she belted out new single If I Were A Boy and hit song Single Ladies.

Beyonce also had a long list of people to thank when picking up her prize for Best International Female.

I want to thank my dad Matthew who is here with me tonight, my sisters, my mum and my Destiny’’s Child bandmates. This is such a special moment for me, the Sun quoted her as saying.

Carey, on the other hand, came wearing a show-stopping silver sparkling dress and had arrived 45 minutes after proceedings had started.

She hardly sat down for the show, and after receiving her Lifetime Achievement trophy she swiftly left the show. (ANI)
