Kate Middleton is officially back to work. The Princess of Wales has made a major public return to royal duties in her first state visit since announcing her cancer diagnosis. Kate and husband Prince William welcomed Qatar’s emir Sheikh Tamim bin Hamad al-Thani and his wife Sheikha Jawaher to the UK on Dec.

"The Princess is feeling positive about the future and very much looking forward to representing the royal family at the state visit and beyond," a source told The Mirror prior to the Emir's arrival.

As Buckingham Palace confirms Camilla was suffering from a form of pneumonia, the Waleses step up to kick off the state visit.
