London, Aug 3 - The mother of late British reality television star Jade Goody says her daughter's spirit is upset with her widower after he admitted to having sex with a model just three months after Goody's death.

Big Brother star Jade, 27, married Jack Tweed, 22, in a blaze of media publicity less than a month before she died of cervical cancer in March.

But Tweed admitted last month that he had sex with model Lisa O'Connor in June.

Jade's mother Jackiey Budden was quoted saying Monday her daughter's presence was felt during a two-hour seance with a psychic and that she regretted having married Jack Tweed as 'the biggest mistake' of her life.

The Sun quoted the psychic as telling Jackiey: 'Jade wants to say 'Sorry Mum' for not listening to you. She knows it was the biggest mistake she ever made - but she just wanted to be a princess.'

'She still loves him and knows he loved her, but she's disgusted with his behaviour and thinks it's disrespectful to her memory and to you.'

Meanwhile, Tweed said he felt 'dirty and sick' after his one-night stand.

'I didn't stay the night. I had started to sober up and left after it happened. I felt so guilty that I started crying when I went home,' he told new! magazine.
