Charles Spencer's Touching Tribute to Princess Diana Captivates Hearts

Princess Diana's brother, Charles Spencer, paid tribute to the late royal on the 29th anniversary of her tragic death.

"31 August. My least favourite day," Spencer, 62, wrote via Instagram on Monday, August 31, sharing a photo of a flag flying at half-staff over Diana's childhood home at Althorp House in the U.K.

Diana died at age 36 in August 1997 after being involved in a car crash in Paris. She is survived by her sons, Prince William and Prince Harry, whom she shared with King Charles III.
