Royal expert Katie Nicholl talked about Kate Middleton's chemotherapy experience amid her battle with cancer.

Nicholl told ET Online in an exclusive interview that the Princess of Wales struggled with chemotherapy early on in her fight against the disease, saying, "I think she had a hard time in the beginning. These are strong drugs that she's on, but she's tolerating it better, and she's doing better."

She said that while the royal had a hard start, Kate "is tolerating preventative chemotherapy better."

"We've had reports from members of the public that she's been out and about. I've heard from certain people that she's out with the children. That's a really positive sign," Nicholl continued.

While Middleton is doing better, Nicholl said that the Princess wants to stay away from the public eye while recovering for her safety.

"She's going through very grueling treatment that has really taken its toll on her. While I'm told that she's turned a corner and she's doing better, she's still going to be prone to infection as she goes through this preventive chemotherapy," Katie added.

"She's going to be very careful about who she's coming into contact with. She's not going to want to put herself at any risk. Therefore, being out of the spotlight and being quiet, not entertaining, not being with too many people, really just keeping herself very much below the radar within that tight family that she has, is absolutely paramount to her full recovery."

But to assure the Princess' fans and followers, the royal expert said that Middleton will pick up from where she left off once she fully recovers.

"Everything I hear from the palace, from those close to the Princess, is that she's absolutely determined to get back to the job to pick up where she left off and to do the wonderful work that she was doing as [the] Princess of Wales," she said.

"I think what this shows all of us is how absolutely vital she is to the monarchy. The monarchy needs her, and therefore we need her to be better. She needs that time and space to make a full and complete recovery," she added.

"Her and William are very much driven by what they do, and she's determined to get back... It is her absolute ambition, determination, and intention to be back to work."

On Wednesday, Prince William also gave an update about his wife's health journey at the 80th anniversary of the D-Day landings in Portsmouth, England.

When a veteran asked him about the status of Kate's health, he responded, "She is better. Thanks. She would have loved to be here today."
