Goody died at her home in Upshire, Essex, at 0314 GMT on Mother’s Day with mother Jackiey Budden, husband Jack Tweed and other family members at her side.
Ms Budden asked that the family be left to grieve in private.
“My beautiful daughter is at peace,” she was quoted as saying by the BBC.
Goody was diagnosed with cervical cancer last August while taking part in the Indian version of Big Brother.
After receiving the news in February that her cancer had become terminal, she made it a priority to secure the future of her two sons, Bobby, five, and Freddie, four, with media interviews and by selling the rights to her wedding to Tweed last month to OK! Magazine. The wedding was also filmed for her reality TV series on Living.
Goody previously spoke of her desire to tell her sons about Jesus before she died and that she wanted them to know she would be looking down on them from Heaven.
She was christened with her sons in a short ceremony at the Royal Marsden Hospital in Chelsea, where she was being treated.
Paying tribute to her this morning, Clifford described Goody as “a very, very brave girl”.
“She faced her death in the way she faced her whole life – full on, with a lot of courage,” he said.
