As Katie Holmes prepares to take to the Broadway stage this fall in Arthur Miller's All My Sons, the biggest names on the Great White Way have one piece of advice for her: Get some rest!
Boeing-Boeing star Gina Gershon believes the key to conquering the big stage is to "get a lot of sleep."
In addition to beauty rest, Katie also ought to watch out for her diet, Pushing Daisies' Kristin Chenoweth says.

"It’s about getting lots of rest and eating healthy, but Katie looks like the type who does."
One person who wasn't going to dish out advice to Mrs. Tom Cruise, though, was Mary-Louise Parker, a Tony Award winner in her own right.
"I’m pretty sure she doesn’t need my advice,” the Weeds star says. "She’s a very successful girl."
