Poor Lydia. She was finally allowed to change out of her lab coat and into her glad rags. With these new clothes came the creeping hope that maybe, just maybe, it was time to honour her 26th birthday. For the last few hours, she and the others have been primping and preening in order to be party ready. But when the eye-in-the-sky called the housemates to the sofas to announce a dramatic change to the nomination rules, her celebratory hopes were eclipsed.

"The whole day has gone and they haven't even said 'happy birthday'," she said, water leaking from her smokily made-up eyes.

Big Brother's news that housemates will now be penalised for discussing nominations has stolen her thunder big time.

"Time is fading away," she said, "This is the s**test birthday in the whole of the land."

We're not doctors but this looks like a classic case of the birthday blues.

However, what she doesn't know is Big Brother had a special birthday surprise planned for her all along
