What better way to end the year than to spend it with the one you love? Corny but true especially for lovebirds Selena Gomez and Justin Bieber.

The young couple spent weeks apart from each other as both decided to be with their own families for the Holidays but now that's over they made no delays meeting up for New Year's Eve right after their separate television specials for the end of the year.

17-year old Justin Bieber and 19-year old Selena Gomez celebrated it up all New Year's Eve and Day at New York City's swankiest spot, the Glass House. Right after Bieber's performance on "Dick Clark's New Year's Rockin' Eve" which was hosted by Activision, Selena met up with boyfriend and spent no time apart dancing like contestants of "Dancing with the Stars" on the dance floor.

"He danced with Selena," says a source to Hollywoodlife.com. "[He was] showing off, picking her up and swinging her around like it was Dancing with the Stars."

The couple stuck together like glue while partying all night. Onlookers knew at once who the lovey-dovey couple was because they made no effort hiding their emotions. Public display of affection was high that night but these two did not care.

"There was heavy PDA throughout the night between them both. They're very much in love and have some great close friends and handlers," shared a source as posted on Celebs.Gather.Com.

"They were dancing a lot with all of their friends," says another eyewitness.

"He picked her up swing dancing-style as they engaged in a dance circle, having a dance contest with each other," shares the source on Zimbio.com.

Even with all the attention Justin Bieber was giving his girlfriend that did not stop the singer from actively playing a part as a deejay at the booth. The singer popped up his brand new track titled "Happy New Year" which he recorded alongside Jaden Smith, Will Smith's son.

Both the show and Justin Bieber and Selena Gomez's New Year's Eve date lasted until the wee hours of the morning which was 3 am to be exact. It was definitely one "happy" new year for these two.
