Kate Middleton made a second appearance this weekend since announcing she had completed preventative chemotherapy for cancer, as she continues her return to royal duties.

On Sunday, The Princess of Wales stood on the balcony above the Cenotaph war memorial in London as part of the country’s National Service of Remembrance.

Middleton has never missed the service since she married Prince William in 2011.

The 42-year-old stood alongside Sophie, the Duchess of Edinburgh, as she observed King Charles III and Prince William laying wreaths in tribute to those who lost their lives in military service.

At the event, part of the U.K.’s Remembrance weekend, which celebrates the members of the British and Commonwealth Armed Forces community and honors fallen soldiers, Middleton watched the concert from a balcony with other working royals.

During Saturday’s concert, she paid tribute to her late mother-in-law Princess Diana, donning a pair of Collingwood pearl drop earrings as well as the sapphire and diamond engagement ring which were once owned by Diana.

Middleton’s back-to-back appearances are her first major events since she announced the completion of her chemotherapy in September.

"Although I have finished chemotherapy, my path to healing and full recovery is long, and I must continue to take each day as it comes," the princess said in a heartfelt video announcing the news. "I am, however, looking forward to being back at work and undertaking a few more public engagements in the coming months when I can."
