Vanity Fair quoted a palace aide as saying: "The Duchess's condition is improving but she is still suffering from hyperemesis gravidarum". Kate, 35, joined her husband Prince William, 35, and brother-in-law Prince Harry, 33, at a reception at Buckingham Palace to mark World Mental Health Day.
Thankfully, a new report claims that the worst has passed and the Duchess has not only been able to finally enjoy her pregnancy (she just entered her second trimester), she is also now ready to attend to her royal commitments.
The Duchess of Cambridge appeared to be in good health at the event.
Middleton will be out and about as early as this Tuesday, Oct. 10 for World Mental Health Day.
"She had seen that at the core of adult issues like addiction and family breakdown, unresolved childhood mental health issues were often part of the problem".
"And after years of working with the homeless, and having been called out to multiple scenes of suicide as a search and rescue and then HEMS (helicopter emergency medical services) pilot, I understood the damage poor mental health was causing to our communities and for our families".
Only a few days after that, it was announced that she is pregnant - and with that came news she was suffering from Hyperemesis Gravidarum, an extreme form of morning sickness that forced her to cancel her public duties.
But tonight she made her first appearance, and the Duchess of Cambridge glowed as she stepped in front of cameras.
