Mum-of-four Olivia Opre from Montana was branded "vile and evil" after sharing pictures of big game animals she's slaughtered.
She was on the show today to defend her friend Britany Longoria, who was condemned for posing with a male leopard she'd killed on safari.
Olivia defended the hunters' right to shoot the animals and insisted it gives an income to locals living near big game parks.
She spoke via videolink in front of two stuffed lions which she said she'd killed and boasted of shooting "100 species" on six continents.
When asked whether she had shot a leopard like her pal, she said: "I've attempted to [shoot a leopard] but they are incredibly elusive so so far it's not happened…
"There's an extensive list [of animals I've killed]. I've hunted on six continents, [I've shot] about 100 species."
Defending her exploits, she said: "I get to be a part of these wild places, it's the adventure, it's the pursuit, something that pushes you to a limit, for me hunting is just being in the wild…
"There's a difference between hunting and poaching. Hunting is legal and [it's difficult] when people get death threats for doing something legal."
Viewers were outraged by her views and the pictures she shared, which showed her with a dead rhino and other animals, left many feeling ill.
One tweeted: "Olivia Opre you are a vile, evil excuse of a human being !!!!! #ThisMorning."
Another wrote: "I hope Olivia gets eaten by a lion next time she goes to hunt one. And I hope she dies in agony. #ThisMorning ."
A third added: "Words actually can't describe how despicable this woman is. Olivia Opre YOU are a disgrace to the world. #ThisMorning."
Olivia's friend Britany sparked a huge backlash this month when a picture of her posing with a leopard she killed was shared online.
Her actions were condemned by stars including models Naomi Campbell and Doutzen Kroes who shared their outrage on social media.
Big game hunting is permitted in most African nations because governments say the revenue it generates helps fund their conservation efforts.
Wealthy hunters, mostly from America, pay up to £60,000 to track and kill a fully grown elephant. Other animals popular with trophy hunters are lions, leopards, rhinos, buffalos and deer.
