Hudson also revealed that her faith helped her get through the murders of her mother, brother and seven-year-old nephew.
'No matter what, He's always there - and that's the thing that keeps me,' she told ABC TV's 20/20.
'And I feel that that's the greatest gift. I could not and would not be sitting her talking to you right now, this happy, talking to you without Him. It's my joy.'
She also spoke lovingly of her other joy, 18-month-old son David Jr, who she affectionally calls 'munchkin'.
'He's so sweet - he loves to dance, he loves music. Or if my commercial comes on he goes, 'Mama! That's my Mama!'
'I have the greatest sadness to be sad over - but then look at the joy I have, too.'
