Princess Kate went out on her own engagement Wednesday and showed no signs of being upset by Prince Harry's shocking memoir, Spare, which was released last week.

In fact, according to body language expert Darren Stanton, she was "very confident" and "seemed very comfortable in her surroundings and in her own skin."

While visiting a day care organization in Luton, Princess was beaming as she met with staff and children who were participating in a craft project. She was having a wonderful time and nothing seemed to cloud her mood.

"I don't think the release of Prince Harry's new book had a profound effect on Kate," Stanton told Marie Claire on behalf of Betfair Bingo (opens in new tab).

"From her body language, she appears to be completely at ease and shows no signs of distress or frustration. In fact, she is more confident than usual.

"She is clearly focused on the task at hand and wants to do her best for the venue she is attending. Some might expect her to be upset, but for Kate and William, it's business as usual!"

As expected.

Predictably, Spare did not hesitate to paint Kate in a less than flattering light. Among other things, he elaborated on Kate's heated argument with Meghan Markle and her claim that Kate was responsible for encouraging Harry to wear the infamous Nazi costume.

Prince William has not shown any signs of being off-balance in public, but is said to be "horrified" by his brother's revelations.
