Queen Elizabeth II returned to work on the morning after Prince Charles’ successful 70th birthday party.

Her Majesty was photographed in her raspberry hat with matching coat and skirt on Thursday morning when she arrived at the Anglo-Norse Society centenary reception at the Naval and Military Club in London.

King Harald V of Norway was one of the attendees at Prince Charles’ party in Buckingham Palace. The 81-year-old thanked the monarch for her hospitality after the pair carried out the private engagement without Queen Sonja of Norway.

“Thank you for a nice party yesterday,” King Harald told the Queen (via Express).

“I’m so glad Charles enjoyed himself,” the Queen replied.

“He looked like it!” King Harald said.

The Queen also met Rolf Christophersen, the honorary vice president of the society, and Angela Christophersen, a council member, during her recent outing. The two were the ones responsible for creating an almanac of the history between Britain and Norway using archived materials.

Royal fans that wanted to see a glimpse of the Queen stood outside the Naval and Military Club in London. Some of them were able to give Her Majesty beautiful flowers.

A day earlier, the Queen was at Prince Charles’ bash and gave a heartfelt tribute to her eldest son and the future King.

“It is a privilege for any mother to be able to propose a toast to her son on his 70th birthday. It means that you have lived long enough to see your child grow up. It is rather like – to use an analogy I certain will find favor – planting a tree and being able to watch it grow. My mother saw me turn 70, of course. And she was heard to observe that 70 is exactly the age when the number of candles on your cake finally exceeds the amount of breath you have to blow them out,” the Queen joked (via the Huffington Post).

In the same speech, the Queen also mentioned Camilla Parker Bowles and said that she has sustained Prince Charles throughout the years.
