Lindsay Lohan reported Tuesday for a 90-day sentence that the troubled actress likely will serve in isolation. Wearing dark denim jeans, a gray top, black corset belt and black jacket, the 24-year-old Lohan showed up at the Beverly Hills courtroom about 10 minutes late. After a short hearing, she rose and was handcuffed behind her back to serve her time for a probation violation.
