Lisa Marie Presley has entered rehab to get a grasp on her addiction to prescription medication. Multiple reports suggest the 48-year-old singer has checked into the exclusive and luxurious Hills Treatment Centre in Los Angeles, which charges $400,000 a month.

She has spoken candidly about her challenges with substance abuse in the past. In 2003 she told Paper Magazine: “[I used] cocaine, sedatives, pot and drinking — all at the same time. I just couldn’t be sober… I don’t know how I lived through it.”
