Glamour model Jess Impiazzi, 28, was discussing her lack of assets when she was younger, which led her to get a breast augmentation as she grew older.
She admitted that she no longer wore bras and only wore crop tops to contain them.
CBB contestant Amanda Barrie, 82, jumped in and said: "I'm afraid I'm a little bit the same, only to the fact I don't have any t*ts.

Meanwhile, there seemed to be the first clash of the series as Ann Widdecombe tried to take India Willoughby's bed from her.
Ann's towel had been placed on India's bed so Ann assumed Big Brother had allocated it to her.
