Lindsay Lohan had an unexpected reunion the other night. The “Liz & Dick” actress was dining at Rubirosa in NoLIta at the same time as her 2005 “Herbie: Fully Loaded” co-star, Matt Dillon. “They were at separate tables when they saw each other,” says a spy. “Lindsay got up to greet Matt as he was leaving with friends.” Lohan insisted she’s having a “sober” New Year’s, then jetted to London, which isn’t exactly known for its sober celebrations, to see her latest love interest, the Wanted’s Max George.
