Lindsay Lohan is still shopping for sites to serve her court-ordered rehab, sources say, after reports she’d been eyeing the Seafield Center in Westhampton Beach. Her lawyer, Mark Jay Heller, confirmed to us yesterday that he and LiLo are still weighing five rehab centers around the country and will decide on one this week. “Lindsay is expected to sit with me this week . . . and then a final approval has to be rendered by the court,” Heller said of Lohan’s requirement to report to rehab May 2. Sources added that Lohan, who’s been busy partying at the Coachella festival in Palm Springs, is considering the Betty Ford Clinic in nearby Rancho Mirage. The troubled starlet’s reportedly concerned about being able to take Adderall while in treatment and had said she’d leave rehab if she’s not allowed to pop the prescribed pills. But Heller tells us that’s not so: “She has not, nor would she be poised to, mandate any type of requirements. Nor has she directed me [to a facility that permits] her to use any types of substances such as Adderall. She has to conform and comply with the [rehab center’s] requirements.”
