Liv Tyler, Olsen twins, other stars stay away from Amy Sacco's Bravo show

Amy Sacco has a radically different business project in the works, but unfortunately, we hear a few of her pals want nothing to do with it.

The nightlife impresario is filming test episodes for a Bravo reality show, but a source says some famous faces like Mary-Kate and Ashley Olsen, Liv Tyler, Rachel Roy and Karolina Kurkova won't be making cameo appearances.
"Amy is having trouble securing all the high-profile names she promised producers because some of her old friends don't want to be seen on camera doing reality TV," the insider confides. "She's losing 'cool' points - and friends. This is a really bad idea."

Sacco's empire has taken some hits in the past few years. Though she was once the queen of New York nightlife, most of her clubs have closed, and the ones still kicking are barely relevant. Lot 61 shut down in early 2006, while restaurant Bette made its exit last summer. One-time "It" spot Bungalow 8 is still around but is growing quiet, and we hear its London-based sister club is empty most nights.
