Kelly Osbourne thinks that celebrities who deny taking drugs and let their publicists make excuses for them are only hurting themselves.

Kelly, who has been through rehab twice for addiction to prescription painkillers, said recently: “So many people in the industry are horrible and have people who are always making excuses for them. Like, ‘She’s late because she’s got flu.’ Bull**t! She’s on drugs.”

“I made a decision for people to stop doing that for me and it forced me to get myself together.”
