Ellen DeGeneres insists she hasn't changed her mind about not wanting children.

The TV host married Portia de Rossi in summer 2008, and there has been much speculation surrounding whether the pair will start a family or not.

Ellen appeared on the Tonight Show With Jay Leno, where she was asked about the ongoing rumours that she and Portia are in search of a sperm donor.

"I'm here for your sperm," she deadpanned to the host, before explaining her stance on the subject.

"That is not true. I don't know why people want this. I've said it so many times: We are not going to have a child. And they say that we're looking for the right donor. Although, you would be a good donor, so I'll keep it in mind, just in case. I mean, it would have beautiful blue eyes, and a good sense of humour, and a good shot at a NBC show. We would do well."

Ellen loves been around kids. Although the star would never want a family of her own.

"I don't want to have one. I don't want to have six. I don't want to have any," she said. "They're precious to look at and I love them; we have nieces and I love them very much. [But I] don't want 'em."
