Justin Bieber was spotted Friday night at Maxim Magazine's Super Bowl party after recent reports that he is partying nonstop to cope with his breakup from Selena Gomez. 

The All That Matters singer joined the party where he was surrounded by security, according to People.com. Sources mentioned that the pop star was denied entrance from other parties, and according to TMZ, he slinked his way into the Maxim party through the back door. Security guards apparently made sure the singer was staying safe the whole time he was there. Anytime someone at the party tried to take a picture of Bieber with a camera or phone, the bodyguards took them away.

Sources say all the partying is triggered by his breakup with Gomez, according to a report from Hollywoodlife.com.

"She was the last girl he was able to develop a relationship with organically," a source tells People. "He's had a hard time letting go of her. He uses partying to cope with the loneliness." 

Bieber was apparently on a trip from Panama to Toronto after he was arrested in Florida for accused drag racing and DUI. And after a reported border patrol detainment, he made it to the party late on Friday night.
