The 31-year-old star admits she is incredibly defensive of her brother Jack Osbourne's three-year-old daughter Pearl, so much so that she isn't allowed to visit two parks in the area for shouting at another child and their mother.

She told Meredith Vieira: "I'm so protective of her. I love her so much.

"I've been banned from two parks in the area because this kid was mean to my niece, and I yelled at the child and the child's mother!"

Meanwhile, Kelly previously gushed about her niece being the "most magical thing in the world" but insisted she was "too selfish" to think about having a child of her own at the time.

When asked if she had baby fever following Pearl's arrival, she shared: "Yes and no. She's the most magical thing in the world and makes me want children. But I'm not ready yet. I'm too selfish right now!"

And Kelly's mother Sharon previously revealed herself and husband Ozzy dote on their granddaughter.

She added: "[The best thing about being a grandparent is] that you don't have to discipline and you can spoil, and you can say yes to everything. [Ozzy] is a doting Papa and he's a proud Papa."
