I'm going to go out on a limb here and say BS to Miley having a severe allergic reaction and say that she is in for rehab. 5-27 days inpatient? LOLOLOL! I work in health care and if that girl was having a severe allergic reaction she wouldn't be tweeting and instagraming all over the darn place! She'd be hooked up to monitors, maybe have her skin sloughing off etc. BS Miley!
