It's no secret that celebrities' bodies are under constant scrutiny. If tabloid covers aren't gasping over a star's weight gain, they're blasting a thin figure for being too skinny.This week, Us Magazine posted a picture of a frighteningly skinny LeAnn Rimes out for a shopping date with fiancé Eddie Cibrian. Us contrasted the picture with a photo of LeAnn from less than a year ago, in which she looked distinctly healthier. By "healthier," I mean, "wow, I can't count her ribs in that picture!"

As someone who's never going to fit into a Vogue sample size, I'm no stranger to being shamed for a less-than-perfect body type. But while I wasn't among those who took to the blogosphere to criticize LeAnn's new skeletal physique, I was surprised to see how quickly the comments on Rimes' new look turned into more personal digs at Rimes herself.

"Looks like the 'I'm scared my fiancé is going to cheat on me like he cheated on his wife with me' diet," one online commenter said.

When Rimes took to Twitter to describe her breakfast that morning-"poached eggs, whole wheat toast, and Italian ham w/fresh berries"-a herd of commenters on celebrity gossip blog OhNoTheyDidn't posted a series of comments along the vein of, "that's the food she looked at and then threw away."

Judging someone's personal life by their bodies-and their bodies by their personal life-is nothing new, especially for celebrities.

But looking at some of the comments on Rimes' pictures, I have to wonder: have eating disorders become the new "safe" thing to make fun of someone for?

Don't get me wrong; I know the Internet isn't a fun, cuddly place. But it seems like even ONTD has the occasional post where those scary-skinny celebrities get messages of "get help!" instead of "lol, bulimia." We'd never say that to a peer, so why is it okay to make light of what might be a serious problem, just because someone is a public figure? Shouldn't that be even less okay, since more people will see those comments and incorporate them into their own thinking about disordered behavior?

I'm not saying Rimes has an eating disorder. For all I know, she's just burning plenty of calories at the gym and making up for them with her balanced breakfast.

But if something is wrong, we should be preaching safety-not poking fun.
