Demi and Selena have been friends since they appeared on Barney together years ago. It was just last year that Demi was still speaking fondly of Selena, but it would appear as of late that the two have had a falling out as Demi posted cryptic messages on her twitter account speculatively aimed at Selena.
Demi wouldn't be the first girlfriend to write Selena off as of late. The only one that continues to take her back continually is her on again off again boy toy Justin, which also seems to the be the reason no one else wants to be around her for long.
Who do you think is hotter, Demi or Selena?
