Justin Bieber changed his Instagram name to Bizzle on Saturday - it left his fans wondering if he's abandoning pop to pursue a hip-hop career as a rapper.

Selena Gomez's ex-boyfriend was spotted recording music in the studio with hip-hop star T.I. on the same night he changed his name.

Justin Bieber is rumored to be getting into a serious relationship with singer Katherine Gazda, HollywoodLife.com reports, leaving many fans wondering if he's considering retiring with her.

The newly formed couple met and began dating in late 2013 - around the same time he revealed he would be retiring from music.

Justin Bieber was spotted partying with P-Diddy in an Atlanta nightclub earlier this week, but something was noticeably different - the "All That Matters" singer was not smoking marijuana (as his entourage was) and was only drinking soft drinks.

Many fans receiving news of the teen heartthrob's night out came to the conclusion he may be taking a break from controlled substances for his ex-girlfriend Selena Gomez.

Selena Gomez revealed she voluntarily spent time at The Meadows recovery center in Arizona in January for two weeks, the New York Daily News reports.

"Selena voluntarily spent time at Meadows but not for substance abuse," her rep said in a statement, the New York Daily News also reports.

A source revealed that Selena Gomez frequently mentioned Justin Bieber during her rehabilitation and discussed how he pressured her to try drugs, HollywoodLife.com reports.

"She finally gave into pressure and started smoking weed with Justin," the source said, according to the site.

"His house was the first place she tried it."
