ROBERT Rodriguez and crew are taking over Austin. A Texas-based spy says that while the guru of gore is shooting his new flick, “Machete,” celebrities like Jessica Alba, Robert De Niro, Michelle Rodriguez and Lindsay Lohan “have been camped out” there. Alba’s been spotted at Mexican eatery La Condesa, where “she now orders without a menu,” according to our source. Lohan’s been lying low, but we’re sure she’ll become a regular at a swanky bar soon enough.
