In fact, they partied into the wee hours...
Gomez was by the Biebster's side at his private party at the Glass House following his performance on Dick Clark's New Year's Rockin' Eve.
"He...danced with Selena, showing off, picking her up and swinging her around like it was Dancing With the Stars," a source tells me.
The "Baby" pop star also took over the deejay booth to play "Happy New Year," his new tune with Jaden Smith. Hosted by Activision, Bieber and his guests also played Skylanders Spyro's Adventure.
The bash lasted until three in the morning.
Happy New Year, you two!
