LIV'S LOVE
"I think designers work harder than anybody," said Liv Tyler Thursday afternoon. And so she showed up at the Calvin Klein show in support of her friend, Francisco Costa. Contrary to what one might think, the model-cum-actress isn't exactly a front-row regular and contends she's only been to Marc Jacobs' show, a celeb-fest if ever there was one, twice. "Five years ago, celebrities and actresses didn't really go to shows," she said. Since then, she's been otherwise engaged, raising her three-year-old son, Milo.

But her role as Costa's bold-faced bestie on Thursday allowed her a night off from mommy duties. She hosted a private dinner for the designer at the Waverly Inn, to which she was looking forward that afternoon.

"They told me I get to invite whoever I want. I don't get out much, so I get to see all my friends."

Tyler was seated next to "Heroes" star Ali Larter in the front row. As for the writers' strike, she said: "Well, it looks like it's going to be over. But I'm at fashion week, aren't I?"
