Pop princess Selena wore a metallic Giorgio Armani gown that was low cut and featured a thigh high slit. Her champagne satin dress was elegant but the backless feature added some spice to the outfit. With her hair in loose curls Gomez and Justin looked mature and classy in their vintage gear.
Selena, 19, and Justin couldn't keep their hands off each other and the pint sized Canadian was constantly

The long gown got special attention from singer Taylor Swift who took the time to give the gold Armani number a closer look. The recent paternity allegations didn't appear to have dampened the love between the two as they put on several public displays of affection.
Bieber took to the stage at the awards show and performed his Christmas hit Mistletoe. He was introduced by his best friend and collaborator Sean Kingston before lighting the stage with a smoke filled set.
Dressed in all white, the singer walked from side to side of the stage lighting a string of lights. Justin had tweeted earlier in the week about his excitement at performing Sunday night.
He said: 'AMA blocking rehearsal. @dankanter is here. sounds like fun.'
Dan Kanter, who is Justin's musical director, also tweeted: 'AMA rehearsal. JB is killing it! Just wait until you all see him tomorrow night!!!' As the crowd screamed, Bieber bounced on to stage and shuffled dressed in a pair of LMFAO's trademark Zubaz pants.
Wearing the yellow trousers and a sleeveless shirt with Sexy written on it the teen sensation did his dance and then ran off stage. At the end of the night Selena and Justin jumped back into their vintage Rolls Royce and a tired looking Gomez rested her head on Justin's shoulder.
The Baby Baby singer gave his girlfriend his tuxedo jacket to wear as she started to feel the cold and the pair were chauffeur driven back to their hotel.
