Almost as soon as critics started commenting on Jessica Simpson‘s weight after she appeared in tight denim high-waisted jeans onstage recently, her friends and family stepped up to defend her, including sister Ashlee Simpson and brother-in-law Pete Wentz.


And now even more support is being sent her way, from a slightly unexpected source – ex-husband Nick Lachey, who usually keeps mum on the topic of Jess.


"I wish her nothing but the best and I hope she’s happy – whatever size that comes in,” he tells Extra. "I can’t believe it’s this big of a story and people are making such a huge deal about it. I’ll never cease to be amazed by people’s reactions to things.”


Nick is all about spreading good will these days: He’s currently in Tampa, Fla. with Jimmie Johnson to kick off Super Skins Celebrity Golf Classic, which will raise money for the Nick Lachey Foundation and Jimmie Johnson Foundation.


"The point is for everybody to have a chance to earn some valuable money for their charity," he says. "Everyone who played last year, had such a great time, [they] came back this year. We’re very fortunate."
