New reports have indicated Justin Bieber is not the reason Selena Gomez is having what some media outlets have described as a "meltdown."

TMZ has reported that Bieber has joked that Gomez's drinking habits are the reason she is going through problems now. A source close to Bieber claims the singer and his friends were laughing at the idea that he was a bad influence on the actress because she was the one who was "always drunk" at parties. 

The source went on to tell TMZ that Bieber said Gomez was "competitive" with the drinking, and would drink or smoke as much or more marijuana as anyone at a party. 

Gomez recently admitted to spending two week in rehab in January. However, her reps have denied that she was in rehab for drugs and alcohol, although they never specified what exactly she was doing there.

"Selena voluntarily spent time at Meadows but not for substance abuse," a rep for Gomez tells E! News.

In Dec. 2013, Gomez surprised fans by canceling the Australian leg of her Stars Dance tour.

"It has become clear to me and those close to me that after many years putting my work first, I need to spend some time on myself in order to be the best person I can be," she said in a statement.

After the show cancellations a source told E! News that she "had been working non-stop for six years" and that "she hit a wall."

"She doesn't like to say no, but she just reached a point where she needs a minute. She is not having a breakdown," the source said. "She wants to be the healthiest that she can be and this means taking a little break. But she is fine. She is OK."
