You didn't think that line of reasoning would silence all the speculation and rumors, did you? Of course not. A source tells RadarOnline, "Demi is so fed up with all of Selena's BS. She has given Selena so many chances to learn from her mistakes and grow up and Selena keeps going back to the source of her misery."
That source of misery sounds like a reference to Justin Bieber.
The insider added, "Selena's partying has gotten out of control and Demi simply cannot tolerate it anymore. Selena used to support her sobriety and her recovery, but lately she is just a trigger to Demi."
The source was sure to include mention of Taylor Swift, noting, "Taylor and Demi do not associate with each other because of all of the drama Taylor put Joe Jonas through after they split and she wrote songs about him. Joe is Demi's best friend."
The insider maintains that Demi won't "bad mouth Selena," but adds, "Selena has to go down her own path and Demi can only worry about herself. She just does not have time for Selena's baggage anymore."
