Lindsay Lohan is “extremely knowledgeable” about fashion, according to fashion guru Tim Gunn.

The 23-year-old actress starred as a guest judge on the sixth season of Lifetime’s Project Runway and has been lauded by the program’s consultant.

“I was surprised and pleased by how extremely knowledgeable about fashion and articulate Lindsay Lohan was,” he said. “She’s very young and can be portrayed in ways that aren’t all together flattering, and she was a true statesperson and really weighed in on the designers and what they were doing exceptionally well. And it was really a thrill to have her.”
