Portia de Rossi was on Oprah yesterday to promote her new memoir, Unbearable Lightness: A Story of Loss and Gain. It was an emotional interview as the 37 year-old Portia told heartbreaking stories about struggling with anorexia and bulimia in Hollywood.

She also described how she would erratically exercise on the spot by running and jumping to try and burn off the calories from whatever she had eaten, including a few sticks of gum or some morsels at Thanksgiving with her family. 

Eighteen year-old Disney star Demi Lovato has quit her concert tour with The Jonas Brothers and checked herself into rehab.

Demi is the star of Disney’s Sonny with a Chance and Camp Rock.

A person familiar with the situation previously told The Associated Press that Lovato entered treatment for problems including an eating disorder and cutting herself. The person, speaking on condition of anonymity because they were not authorized to speak publicly due to the sensitivity of the matter, later clarified the statement, saying Lovato had dealt with those issues in the past.

It’s always like waiting for the other shoe to drop waiting on these Disney kids to freak out. At least she is getting help now, maybe she’ll get better and not end up like Britney Spears or Lindsay Lohan.

White House gate crasher and Real  Housewife of D.C. Michaele Salahi is defending herself against the eating disorder rumors that her castmates started in this week’s InTouch.

44 year-old Michaele says she’s just always been a skinny girl and if her cast mates’ would get out there and move, they will look like me and be thin, and it’ll all be good.’

What’s your diet like?

I start the day with a hot chocolate and cereal — I love Lucky Charms or Kashi GoLean — then some fruit. I don’t really eat a lot in the middle of the day. I have an early dinner, which is always a salad, with plain chicken, grilled or broiled.

What about plastic surgery — would you ever do it?

Definitely. I would love to do a whole lot of Botox and maybe get collagen, too. I also think it would be great to have boobs. I’m a B [cup], so I’d get a C. I’m all for anything you can do to make yourself look and feel better.

Although Kai Hibbard had great success on the show with a total weight loss of 118, she is accusing The Biggest Loser of being responsible for her developing an eating disorder. She claims it got so bad her hair fell out and her family and friends had to stage an intervention before she started eating again.

“I found myself loathing what I looked like the more weight that I dropped because of the pressure on me,” Hibbard said. “I found myself doing things like considering coffee a meal. And because of the pressures on the show it was considered acceptable to behave that way.”

Hibbard also alleged the show misrepresented how much time had passed – it was often more than a week – and encouraged contestants to exercise while severely injured and diet by dehydration to make the numbers on the scale drop dramatically.

“Before I went on the show I never learned how to dehydrate to manipulate a scale,” she said. “And when I left I knew how to do it better than some fitness competitors.”

Four years after the fact, Nicole Richie has decided to address that whole “Rachel-Zoe-sickly-skinny” phase she went through back in 2006.

Remember this:

In the March issue of British Marie Claire, Nicole talks about that dark time.

Richie, who was once a size 0, caused some fans to worry in 2006 when she was photographed looking alarmingly frail on the beach in a bikini. Around the same time, she addressed her thinness in Vanity Fair: “I know I’m too thin right now. I’m not happy with the way I look right now.”

“I felt it was a little unfair to say someone has an eating disorder when they don’t,” she says. “It’s extremely insulting and irresponsible. An eating disorder is serious and it’s a disease.”

I’ve always believed that Nicole was not suffering from an ED but got caught up in the high fashion-sample-size-Rachel-Zoe world for a minute. She definitely starved her body for a short period, lived a very unhealthy lifestyle and in the end paid for it with a DUI arrest.

Strangely enough, she came out the other end a healthy young mom with a thriving career and business. For every three Brittany Murphy’s..Hollywood spits out one Nicole Richie. Not ideal but at least there’s hope for so many other confused and pressured young celebrities.
