She was the villain of The Bachelor
– and one of the biggest lightning rods in the ABC franchise's history – but the host of the show thinks Tierra LiCausi
was genuine on the show ... for better or worse.
"She's sincere," Chris Harrison told PEOPLE Thursday. "People will think [the way she acts is] fake or it's made up. It's not. This is how she goes about finding a man. Once you shine a light on it and put a camera on it, it's not attractive, but that's how she does it."

"I can't wait to talk to her next week at the Women Tell All," Harrison said of LiCausi's engagement while attending the Club SI Swimsuit party at Vegas's 1 OAK. "It's not to back the bus over her. I kind of want to know what she sees."
Harrison is well aware of the public perception of LiCausi, but he can't rank her in terms of "all time Bachelor villains".
"She was her own character so I don't think I can rank them," he said. "I think it's the way she went out put the cherry on top when she said, 'No one's gonna take my sparkle away'. You just can't top that."
