As international interest continues to swirl about the health and appearance of Princess Kate, Prince William is said to be “deeply frustrated” over the mounting speculations regarding his wife.

Royal Correspondent Rhiannon Mills conveyed the current mood of the Prince while addressing the media during his visit to Sheffield as part of his homelessness project on Tuesday, as per Sky News.

“I’m told he’s deeply frustrated by the fact that interest in Kate isn’t dying down but you wouldn’t know it today,” Mills shared.

Scrutiny of the Princess’ appearance remained a topic of discussion as many expressed apprehension over a recent video of the Royal in public for the first time since December.

The video comes on the heels of the “photo fiasco,” last week. The “Mother’s Day” family picture posted to the couple’s page was later retracted by news agencies due to manipulation.

The Princess of Wales has since taken responsibility for “any confusion” caused by her experimentation with photo editing, which would have been her first picture since being hospitalised for an abdominal procedure in December.
