A pregnant Princess Eugenie could not stop shedding tears as she and her sister, Princess Beatrice, heard a tragic story while participating in the commemoration of the Teenage Cancer Trust's 30 years.

The York princesses had been speaking with nine honorees via a virtual platform when they came across Enid Waterfall. The 85-year-old grandmother shared that she lost her 21-year-old grandson, Richard, to a rare form of cancer.

Despite the tragic outcome, Waterfall was more than determined to help raise funds for young people living with cancer, assisted by the Teenage Cancer Trust. The grandmother said that she feels a lot closer to her grandson when she's doing her work for charity.

Eugenie commended Waterfall for the amazing way she's honoring her grandson. The royal said she was choked up to realize that it must have been a tough thing to do when feelings of loss are still ever-present.

The princess was seen wiping her tears as she spoke with Waterfall, and her sister was also drying her eyes as they thanked the participants of the virtual commemoration.

Princess Eugenie and Princess Beatrice have been working with Teenage Cancer Trust, alongside their mother, Sarah Ferguson, for years. The royal, expecting her first child with Jack Brooksbank in early 2021, is also the co-founder of the Anti-Slavery Collective, which focuses on stopping human trafficking and modern slavery.

She also had a virtual chat with the said charity on Instagram, where she shared her lockdown experiences with a baby on the way. The York royal acknowledged that she's lucky to have her health, but she cannot imagine the struggles of those who are getting sick because of the COVID-19 virus.

In March, the Brooksbank couple was personally affected by the virus when Jack's father, George Brooksbank, contracted COVID-19 after a trip to France. Eugenie said that George had been quite ill, but she's grateful that he's still alive, fighting, and recovering.

Meanwhile, Eugenie and Beatrice are currently unable to see each other because of the second lockdown in the U.K. This means that the family wasn't able to celebrate together as Beatrice's husband, Edoardo Mapelli Mozzi, turned a year older on Nov. 19.

Three days prior to Edo's birthday, Beatrice said in a video message for the Northwood African Education Foundation (NAEF) that it has been quite a challenging year but she remains thankful that charities continue to do their work. The NAEF is launching an online auction to raise funds for their beneficiaries. Beatrice, who advocates for education as someone who suffered from dyslexia, is the patron of the NAEF.
