Ananova:

Nadia has told Big Brother she feels guilty after chatting with Shell about having children.

The transsexual housemate was quizzed about whether she wanted babies.

Nadia revealed she couldn't. Shell then asked why, adding: "Wouldn't you want to try IVF?"

Big Brother intervened and called Nadia to the diary room where she talked about her discussion.

"I feel guilty because I have to make up a story to explain why I can't have children... I don't want to lie... but I'm not ready to be honest with the housemates, not yet."

When asked how she thinks the housemates will respond, Nadia said: " I don't think they'll be shocked - more question why I didn't tell them. If it was obvious, I'd be very disappointed."

She added: "It's come up sooner that I thought!"

Nadia also talked about Ahmed, who has come closest to discovering her secret: "He came up to me saying that I am such an intriguing person. He is suspicious of me."
