We caught up with Prinz Tuesday after his lunch at Il Fornaio in Bev Hills, and he broke down this adoption ... saying Kevin Feucht was the perfect fit of several options, and he's happy with his choice. For now.
He even said Zsa Zsa would like Kevin too -- they'd actually met back in the day, and Prinz said she'd tell Kevin ... "You're so cute. I want to adopt you."
But, then Prinz told us nothing's written in stone here. He says Kevin's gotta keep performing at a high level if he wants his inheritance and title.
As he put it, "If he's bad, I get another one. If the other one is bad, I get another one. I can adopt as much as I want."
