ONTARIO, Canada (SS) That didn’t last long.. Justin Bieber and Selena Gomez are back together. The pair - who split less than two weeks ago - were spotted hand in hand together at the star-studded after party for the American Music Awards in Los Angeles Sunday night. Selena did not attend the 40th annual awards ceremony, where Justin performed, but helped him celebrate at the Marriott Downtown Hotel after he won three prestigious awards.
