- The public may know him as the Duke of Edinburgh, but Prince Philip is also a loving grandfather.
- He was there for two of his grandsons, Prince William and Prince Harry, when their mother, Princess Diana, died.
- He was also supportive of his grandchildren Peter and Zara Phillips' studies and visited them at school.
The public may know him as the Duke of Edinburgh, but to his eight grandchildren and eight great-grandchildren, Prince Philip is just their granddad. Through the years, Prince Philip has been a supportive grandfather who has been there for them and watched them grow.
In honor of his 99th birthday on June 10, here are photos that show Prince Philip is just a regular grandpa.
