Is Demi Mad At Selena???

Best friends Selena Gomez and Demi Lovato might not be those best friends Selena Gomez and Demi Lovato anymore! Yes I know it is shocking! Rumors have it that gossip sites think Demi Lovato is mad, because at previous CD signing someone asked about Selena, and she answered:
"Ask Taylor."
Oooo! I wonder why they aren't that bounded anymore. Selena does say that Taylor has been a big support for her "Kiss & Tell" album, she never mentioned anything about Demi helping. Jealousy maybe? Well that will all be revealed in time.....
