Lindsay Lohan cried on Letterman’s couch about how rehab was serious business and she took it seriously because it could change her life for the better. Only to immediately go out drinking and ask Siri the location of her nearest dealer so she could stock up before doing a bunch of drugs at Coachella. And because she doesn’t give a s**t despite being warned about tardiness by Scary Movie 5 producers, OF COURSE she showed up late to the premiere where she was Charlie Sheen’s date. Making that at least two times she’s left him waiting around for her after turning up four hours late on the second day of Anger Management. RadarOnline.com reports, Lohan was 30 minutes late. But at least she looked like this which is… good… for her. Photos of the Scary Movie 5 L.A. premiere below.
