Crocodile Hunter Steve Irwin's widow broke down in tears during a recent taping of The Oprah Winfrey Show in Sydney, Australia as her young son revealed he watches videos of his late father every day.
Little Robert, who is the spitting image of his conservationist father, told Oprah and her audience that watching the footage makes him feel that his dad "is actually there".
The six year old added, "He was the best dad." Terri Irwin was touched by her son's words and started to cry.
She regained her composure to pay tribute to her late husband, who died after he was pierced in the chest by a stingray barb while filming in Australia's Great Barrier Reef in 2006.
She said, "Living with Steve was like standing in a cyclone... and then when we lost him, it was like the wind stopped. It was really hard."
Irwin then broke down as she thanked her husband's fans and friends for all their support in the past four years - particularly towards the Australia Zoo he founded.
She added, "Everybody here is making sure that Steve's legacy continues."
