Princess Kate is "not ready to return to work" after her cancer diagnosis but is "keeping an eye" on the report by the Royal Foundation Centre for Early Childhood, according to GB News' royal correspondent Cameron Walker.
The princess had been briefed on the report by the charity, which calls for more business investment in children's early years.
Speaking on GB News, host Isabel Webster said: "It's characteristically Catherine, isn't it? To say she wasn't doesn't want to distract from this report by having people talking about her health.
"We should start probably by saying she said she's not feeling well enough to come out and talk about this in public, but she is saying she's watching it, keeping a close eye from behind closed doors."
Princess Kate is "excited" by the report
GettyCameron said: "This should not be seen as a return to work by the Princess of Wales, but I have been told she's read the report and has been briefed on it.
"But this will stem from her work from when she started being a working member of the Royal Family, where she was working closely with people suffering from addiction and mental health problems."

"What she found is all of these issues tend to stem from a poor start in life. So the first five years of a child's life."
Cameron added that the princess has been described as the "driving force" behind the charity.
He said: "It's a big task, isn't it? That's a lot of change that would need to happen. So it's going to happen over a long period of time.
"The princess cannot lobby the government. She can't be political. So I think she's trying to encourage the private sector to do as much as they can in sport and create societal change."

The Princess of Wales revealed in March she was receiving treatment following a cancer diagnosis.
That followed an announcement in January that the princess had undergone abdominal surgery.
This latest information suggests nothing has changed since the previous calls for privacy while she recovers.
A royal aide stated that Kate will only return to royal duties once she has had the "green light" from doctors.
