Arriving in a white Rolls Royce and channelling old Hollywood glamour in vintage ensembles, the couple posed together affectionately on the red carpet.
And in true gentleman fashion, 17-year-old Justin – smart in a black tux and bow tie - held his 19-year-old's girlfriend long, flowing train as they made their way inside.
The gorgeous Disney star was wearing a shimmering silk, backless Giorgio Armani gown with a champagne hue that perfectly set off her olive skin.
And other attendees had the same idea. Taylor Swift, Jennifer Hudson and Heidi Klum were just a few of the guests who had opted for metallic gowns.
Artist of the Year winner Taylor wore a gold sequinned floor length Reem Acra gown, whilst Jennifer showed off her impressive weight loss results in a silver Jenny Packham minidress.
And supermodel Heidi put her endless legs on display in a laser cutout silver minidress.
The dazzling set joined a host of famous faces including Katy Perry, Ellie Goulding and Mary J Blige.
Quirky popstar Katy wore a white, Chinese-style sequinned Vivienne Westwood dress and her famously colourful hair had been dyed a purple hue.
The starry crowd was treated to a show-stopping, acrobatic performance from Jennifer Lopez, followed by her ex-husband Marc Anthony and Mary J Blige.
