Justin Bieber, Selena Gomez: Bad Boy Biebs Parties All Night in NYC With Jaden Smith & Girls for 'After Earth' Premier, Without Alleged Girlfriend

Justin Bieber was out until 6 AM this morning after spending the night with actor Jaden Smith after the New York City premier of the movie After Earth. Not only was the "Baby" singer out for so long, he only went back to his hotel room for about 30 minutes before hopping on a plane. Reports claim that the two teenage stars were club hopping and even had an entourage of party girls with them. Unfortunately for Bieber, his on-again, off-again girlfriend Selena Gomez is reportedly testing him out to see if restarting the relationship is a good idea. Looks like he might have ruined things with the Spring Breakers actress.

"He partied at Marquee, went through the back door at 1Oak and then left and headed to Avenue," an insider told HollywoodLife. "At Avenue he went through a secret entrance. They picked up a couple girls along the way."

Justin is currently taking a month off from his "Believe World Tour," and it looks like he is definitely enjoying the time off.  But as you can see, Selena Gomez was not with him last night after the two reportedly started dating again. Plus the fact that "a couple girls" were picked up along the way does not bode well for the newly rekindled relationship. 

Friends of Gomez have claimed that she has warned the pop star to be on his best behavior in order for them to start dating again. Right now they are on a "trial period" before Selena can decide whether or not to rekindle their romance.

"Justin and Selena are dating but they are taking things slow," a source explained last week. "Selena is keeping her heart from being broken, so she is definitely looking at this as a trial period in their relationship."

Justin is also being investigated for reckless driving after exceeded dangerous speeds while speeding around in his Ferrari in his neighborhood.
