Lachey: 'Simpson Weight Ridicule Is Ridiculous'

The photos prompted speculation about her weight gain, with the star's sister Ashlee branding the media attention "embarrassing and belittling" in an angry rant on her blog.

And now Lachey, who was married to Simpson for four years before their divorce in 2006, has waded into the debate.

He says, "I think it's ridiculous that the media is making such a big deal about it. It's ridiculous that it would be making headlines. But you can't believe everything that's written or reported in the media.

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

And fellow curvy star Carmen Electra has defended Simpson's decision to flaunt her body in revealing clothes.

She tells People.com, "She's a gorgeous girl. A lot of women would die to look as good as she looks. There's going to be moments where people don't necessarily like your look or what you're wearing, and that's okay. Next week, she'll rock some outfit that will blow everyone away."
