Prince William spoke about the special bond his kids Prince George and Princess Charlotte shared with their great grandmother. The 33-year-old royal was speaking at a garden party organized in honor of Queen Elizabeth II’s upcoming 90th birthday on April 21. The event was hosted by the British High Commission in New Delhi on Monday.

William and his wife Kate Middleton toasted the queen, who became the longest-serving monarch in September. They met around 2,000 VIP guests from local Indian politics. “I hope you don’t mind if I take the opportunity to pay tribute to the Queen on a more personal note. I’m incredibly lucky to have my grandmother in my life,” he said.

The 33-year-old prince added that his grandmother was “remarkably energetic and dedicated guiding force for her family.” The prince paid a touching tribute to his grandmother, and called her “the boss.” William added that George and Charlotte were very “lucky” to have her as a role model.

As an emissary of his 89-year-old grandmother, William read out the message from the former and his grandfather Prince Philip. Elizabeth said in her message that she had “fond memories” of her visits to India. She added that she passed on the responsibility to another generation of her family to strengthen and renew the bonds of the two countries.

The party was held at the residence of the British High Commissioner in New Delhi. Guests were treated to traditional Indian music and dined on a mix of Indian and British food. William and his wife Kate cut a special birthday cake for the queen that had the emblem of the British flag with a ceremonial sword.

On Day 3, the royal couple is scheduled to meet the Indian prime minister Narendra Modi and have a sit down lunch with him. William and Kate will then leave for Kaziranga National Park in the northeast Indian state of Assam, where they are likely to stay at the IORA resort. Prashanta Kumar Sharma, general manager of IORA resort, said the hotel employees were planning to welcome the royal couple with traditional dances and serve them traditional dishes, along with one of the world’s hottest chili, known as bhut jolokia (ghost chili pepper).
