Opening arguments are scheduled to begin April 23.
Potential jurors in the trial were given questionnaires which asked if they were familiar with Hudson's career, if they regularly watched "American Idol," and even if they were members of Weight Watchers, a weight-loss program for which Hudson is a celebrity spokesperson.
Most of the jury panel was chosen Monday with the final four picked on Tuesday. The jury is composed of 10 women and eight men and is racially diverse.
Jurors Asked Not to Watch 'Idol'
While waiting for opening statements later this month, Judge Charles Burns asked the jurors not to watch the television show "American Idol," because Hudson was scheduled to make an appearance on an up-coming episode.
Balfour, the estranged husband of Jennifer's sister Julia, is accused of shooting their mother, Darnell Donerson and their brother Jason at the family's home on Oct. 24, 2008. Julian King's body was later found in an abandoned SUV.
The trial is expected to last about a month.
