Here's hoping Justin Bieber and Selena Gomez can maintain the same fevered level of excitement for each other that they enjoyed on New Year's. E! News says the petite pair had a serious case of happy feet while partying at a private bash at New York hot spot Glass House after their respective TV appearances.
"[Justin] danced with Selena, showing off, picking her up and swinging her around like it was 'Dancing With the Stars,'" bubbles an onlooker.
Another spy tells Hollywood Life that in between busting a move with their pals, Bieber and Gomez put their rug-cutting skills to the test: "He picked her up swing dancing-style as they engaged in a dance circle, having a dance contest with each other."
