Selena Gomez or Demi Lovato?

I like both but Demi Lovato has had a hard year she's been in and out of rehab because of insecurity and drug issues, but Selena is dating Justin Bieber and I'm sure it's just for show personally I hate when celebrities date it makes her look trashy. Selena has been supporting Demi though...I think both have their ups and downs in beauty and life.
