Are Lindsay Lohan and her father, Michael Lohan, estranged once agan? The New York Post's Page Six column is reporting that the starlet left the Peninsula Hotel in New York on Wednesday (where she'd checked in with galpal Samantha Ronson the day before) because she knew her father was looking for her. "Michael found out where Lindsay was going to be and went to find her," an insider tells the paper. "She was really freaked out by it because she has no interest in seeing her father." Lindsay apparently went to have dinner with her mom, Dina, and sister, Ali, instead — leaving her dad to wait for her at the hotel. "Michael was staking out the lobby and waiting for Lindsay to make an appearance," reveals the insider. "It was freaky. He was sitting on the steps and texting like mad, and looking very upset that she hadn't arrived."
