This is such a wonderful story!  I have said before how much I ADORE Demi.  I think the fact that she is being so open and honest w/ her fans about how she is a real person and struggles like everyone else is literally saving lives.  And now that Selena supported her by doing this?  It just shows they take their "job" very seriously.  

TMZ reported that Demi, who actually lived in a sober living home for more than a year, showed up to speak to a recovery group (something she rarely does), and Selena came along for the ride to support her.
