The rumors about Kate Middleton suffering from post-partum depression has not died since Prince William's wife gave birth to Princess Charlotte on May 2.

Now, Celebrity Dirty Laundry ran an article that suggested Kate Middleton was jealous of Prince William's plans of attending the wedding of his ex-girflriend Olivia Hunt.

Prince William and Olivia Hunt dated when they attended St. Andrews together, and although they split-amid rumors that Kate Middleton was the reason-the former couple remained friends. Hunt is now set to marry barrister Nicholas Wilkinson.

"However, it's no secret Prince William and Kate Middleton are having marriage troubles," the article claimed. "The two secretly split while Kate was pregnant with Princess Charlotte. William didn't see Kate for an entire month, but Queen Elizabeth reunited the two and the royal couple returned to smiley public appearances."

"Some have suggested that Kate is suffering from post-partum depression and this accounts for her almost total absence from public life since Princess Charlotte's birth," it added.

The rumor about Kate Middleton allegedly suffering from post-partum depression is not new.

In June, Closer Weekly reported that the Prince William's wife Kate Middleton is dealing with the "baby blues."

Psychologist Julie Armstrong told the site, "Kate's trying to juggle it all and is really feeling the pressure."

"Giving birth is a huge undertaking, and then there's the stress and strain of family and a baby whose needs are 24/7. So now she's competing - where does she put her needs? To which baby does she give her attention? All which is a drain on her own resources - her psychological resources," she added.

The maternal website Rosie Pope also noted in a blog post that Kate Middelton's post-partum depression, if true, is understandable but there's treatment out there for mothers who are going through the same thing.

"Postpartum depression isn't something that women can turn on or off like a switch or decide to talk themselves out of," it said. "It's a hormonal imbalance that can be tricky to diagnose and even more challenging to treat, especially if the mother is breastfeeding."
