Selena Gomez really took her rehab stay seriously. Apparently she was supposed to stay in rehab for six weeks but decided she was cured after two weeks and had important things to do like go promote her movie which is a huge bomb. I have seen two people do rehab correctly in the past few years. Demi Lovato and Ke$ha. Each of them not only stayed the time they were supposed to but also additional time and, in the case of Demi forced the need to make a big splash when she emerged after many months inside the facility. Ke$ha always has songs playing on the radio and checked herself in at the time her latest song was just entering the Top 40 so will stay relevant even while getting healthy. She is staying longer to make sure she is recovered. She didn't bail early. All this means for Selena is that unless she is like the vast majority of people who leave rehab early that she will need a repeat visit in the very near future. Right now she thinks she can do it all herself and when the inevitable slip does happen she will probably slip up really badly. The promoting a movie thing doesn't really fly for me because she already canceled her Australia tour so she had the time off. The simple excuse was she was tired of rehab and thought she knew best.
