UPDATE: Monday, April 23, 2012

Jennifer Hudson says her family didn't want her sister to marry the man now accused of killing her mother, brother and 7-year-old nephew.

Hudson's voice broke Monday as she testified on the stand about how she reacted when her sister told her she was going to marry William Balfour. Prosecutors say he killed the Oscar winer's family after becoming enraged that Hudson's sister, his estranged wife, had begun dating someone else.

Hudson struggled to hold back tears as she told jurors, "None of us wanted her to marry him." She added, "We did not like how he treated her."

Balfour has pleaded not guilty to three counts of first-degree murder in the October 2008 slayings.

Hudson previously has declined to talk publicly about the killings.

A court official says Oscar-winner Jennifer Hudson has arrived at a Chicago courthouse for the start of the trial of a man accused of killing her mother, brother and nephew.

Courtroom spokesman Terry Sullivan says Hudson is in the building, but will not be in court for opening statements. He didn't elaborate.

The 30-year-old actress and singer is among a list of 300 potential witnesses who could be called.

William Balfour, the estranged husband of Hudson's sister, is charged with first-degree murder in the 2008 slayings. Prosecutors say Balfour shot them in 2008 in a jealous rage because his estranged wife, Julia Hudson, had a new boyfriend.

Julia Hudson has said her sister screamed when she told her about the murders.
