INSIDE KATE'S BIG COMEBACK

Princess Kate gives an update about her ongoing cancer battle before returning to the spotlight at the king's birthday parade

- 

A head of the June 15 Trooping the Colour in London - her first official appearance in six months - Princess Kate shared an update on her cancer treatments, which she said will continue for a few months.

"As anyone going through chemotherapy will know, there are good days and bad days," Kate, 42, wrote on social media. "On those bad days you feel weak, tired and you have to give in to your body resting.

But on the good days, when you feel stronger, you want to make the most of feeling well."

If Kate's glowing smile at King Charles III's official birthday celebration is any indication, her public return was definitely a good day! "Kate was nervous making her reappearance," reveals an insider.
