Jennifer Hudson said eternall farewell to her mother Darnell Donerson, brother Jason Hudson and nephew Julian King as they were laid to rest at Chicago's Apolistic Church Of God at the start of the week, according to the Chacago Tribune.
All three were murdered last month in Chicago.
American Idol's Fantasia Barrino sang at the funeral of the Hudsons.
Barrino performed Your Grace and Mercy at the service, calling the Hudsons "my family". Hudson and Barrino competed in the finals of the 2004 series.
The Reverend Jesse Jackson and Chicago Mayor Richard Daley both spoke at the service.
According to the Associated Press, streets were shut down by police, and a plastic covering was used over a tall gated fence to protect the family's privacy. The murders have yet to be solved.
Jennifer Hudson won an Oscar for her role in Dreamgirls alongside Beyonce Knowles.
