Prince Harry and Queen Elizabeth had a 4-hour private lunch during his return to the U.K.

Prince Harry got in some quality time with his grandmother, Queen Elizabeth II, over the weekend. A royal source tells ET that the 93-year-old reigning monarch had a four-hour lunch with the 35-year-old Duke of Sussex on Sunday. 

This is the first time the two have been face-to-face since they agreed Harry would exit his senior duties. In January, Prince Harry and his wife, Meghan Markle, announced their intention to step down as senior members of the royal family. 

After several discussions with Queen Elizabeth, Prince Charles, and Prince William, the family came to an agreement that Harry, 35, and Meghan, 38, would no longer be senior royals, would split their time between North America and the United Kingdom and would become financially independent from the royal family.
