Jessica Simpson's ex-husband, Nick Lachey, spoke out over the bad publicity she's been getting over her new curves.

I wish her nothing but the best, and I hope she's happy - whatever size that comes in, he told Extra.

I can't believe it's this big of a story and people are making such a huge deal about it. I'm never ceased to be amazed by people's reactions to things.

Simpson, 28 and Lachey, 35, and were married from 2002 to 2006 and starred in the successful MTV reality show Newlyweds: Nick & Jessica for three seasons.

Simpson is now dating Dallas Cowboys quarter back Tony Romo, while Nick is with vanessa Minnillo.
