It's no secret Dems was a hardcore partier back in the day before she decided it was time to change her life and shipped herself off to rehab!
Now that she's a changed woman, her so-called "friends" back then have been dropped from her contacts list!
"I look at my past and I think, 'OK, it was fun at the time, but looking back I don't remember a lot.' I had birthdays where there were a ton of people and everyone was drinking and going crazy.
None of those people are still in my life today. Because they didn't care about me and … I didn't really care about them — I just wanted to party."
It's a great thing she realized that and left those people in the past to focus on her newly sober life!
We imagine life would be very different for the pop star if she kept in touch with those people after she left rehab!
