Linsday Lohan may blog about her lessons learned after rehab, sources tell Page Six. We hear the troubled actress is in talks with Web site Celebuzz to detail her deepest thoughts after her 90 days of court-ordered rehab. We're told Lohan would contribute content beginning in August, after the rehab stint, which will reportedly start Thursday at the Seafield Center in Westhampton Beach. Her next step would be to launch her own site with her musings on art, fashion, music and movies. Lohan was expected to meet with Celebuzz editors to hash out ideas, but their consultant A.J. Daulerio tells us, "I'm still waiting for the official grooming session." Perhaps he should hang out at 1Oak in the morning hours. Spies saw Lohan this weekend at the Chelsea club at about 2 a.m., joining a large party seated near the DJ station. But several other mortals were sitting on the edge of the banquette, close enough to annoy Lohan. That's when, according to a spy, "Security emerged from where Lohan was and told them to move away. Lindsay thought they were spying on her."
