LINDSAY LOHAN'S HALF SISTER HAD SURGERY TO LOOK LIKE LINDS: If imitation is the sincerest form of flattery, then LINDSAY LOHAN should be flattered. But she's probably creeped out. That's because her estranged half-sister Ashley Horn has gotten $25,000 worth of plastic surgery to look more like Linds. Ashley showed off the manufactured resemblance in the new issue of In Touch.

The 18-year-old, whose mom had a brief affair with Lindsay’s dad (while he was still married to now ex-wife Dina), explains, "I've gotten rhinoplasty, a bit of refinement underneath my cheeks and jawline, some fat injected into my chin and some fat injected into my upper cheeks." (BEFORE)

Her goal, she adds, "was to look like Lindsay in her good days, when she was around 18, 19 years old." And she thinks she achieved that goal and more. "I’m hotter than Lindsay! I have no problem saying that." Is she? We Report, You Decide! (PHOTO)

UPDATE - LAMAR ODOM MAY NOT HAVE WRITTEN ANGRY TWEET DIRECTED AT HIS FATHER: Sources with "first-hand knowledge of Lamar's actions" tell TMZ LAMAR ODOM did not write that angry Tweet we told you about yesterday in which he ripped into his father and defended and praised the KARDASHIAN KLAN. The site claims that where Lamar is holed up at, he doesn't even have Internet access, and that he has no idea his father even did an interview blaming the Kardashians for his problems.

As for where exactly he's holed up at ... the site's "multiple sources" say it's a home "in a gated community 100 miles from L.A." which is basically just a high rent crack den, because sadly, the sources also claim he's still hitting the pipe hard. Lammie and his best friend are supposedly "smoking crack and partying with 2 young women," one of which Odom is allegedly getting all smoove up in.
