Justin Bieber and Selena Gomez opted to dress up in wardrobes that were years beyond their ages, but the young couple seemed to pull it off nicely.

The lovebirds wowed the crowd when they arrived and left in a white vintage Packard Super 8 which was notably used in the 1930's and 1940's by Hollywood's finest.

In style with their outfits, the pair channeled Hollywood's most glamorous era when they arrived at the Nokia Theater in Los Angeles. Justin took it all out by being a gentleman and helping his beau lift her trail to avoid stepping on it.

Justin wore tuxedo with his hair slicked back and his ladylove Selena wore a stunning metallic Giorgio Armani low cut gown with a sexy slit. Her gown received special attention from Taylor Swift as the country singer was snapped giving it a closer look.

The ongoing paternity allegations against Bieber didn't seem to affect their relationship as the two did several public display of affection. Bieber also took the stage when he performed his Christmas single "Under the Mistletoe."

Bieber lost the Best Pop/Rock Male Artist of the Year awrd to Bruno Mars but the teen sensation didn't seem sad or affected. Later that night he tweeted:

"Happy for my dude @brunomars - couldnt have gone to a better guy. well deserved. and @taylorswift13 and @NiCKiMiNaj CONGRATS Ladies!"

At the end of the night the couple hopped back into their vintage car where Selena rested her head on Justin's shoulder. He gave his girlfriend his tuxedo jacket for the cold journey back to their hotel.
