Hudson also talked about how she lost 80 pounds. She said on Thursday's "The Oprah Winfrey Show" that her fiancé has had trouble adjusting to the attention other men are paying to her since she dropped from a size 16 to a size 6.
Hudson has been a spokeswoman for Weight Watchers.
In October 2008, the bodies of her mother, Darnell Hudson Donerson, and brother, Jason Hudson, were found in the family's Chicago home.
The body of her 7-year-old nephew, Julian King, was found days later in a sport utility vehicle about 10 miles away. All three had been shot.
