Molly Sims

Molly Sims has a simple message when asked about her former Las Vegas costar Josh Duhamel's rumored infidelity: "Don't believe everything you read.""We e-mailed yesterday," she tells E!'s Daily 10 on Wednesday. "It's absolutely not true – and he's a great guy. I've worked with him for five years."

Remember that post about Mischa Barton’s nutty new workout routine? Here she is in action. And apparently, she’s not the only starlet flying high in Jukari class. Molly Sims is also attending the hour-long flight class.
