Expert: Jennifer Hudson Could Affect Family Murder Trial's Outcome

Jennifer Hudson claims she'll attend her brother-in-law's murder trial, gavel-to-gavel.

As jury selection began Monday, analysts told E! Online that might be among the worst possible things she could do if she trulyl wants justice. William Balfour stands accused of an October 2008 rampage in which he shot and killed the former "American Idol" runner-up and "Dreamgirls" Oscar winner's mother, brother seven-year-old nephew.

Prosecutors and Balfour's defense will start with a 150-juror pool, and ultimately select 12 that will declare Balfour's innocence or guilt. Nine questions out of each juror's 66-item questionaire reportedly directly referenced Hudson's career and fame. One item asked if the responding juror had seen "Dreamgirls" while another asked if the respondent was a patron of an organization Hudson had previously publicly promoted - such as Weight Watchers, which has employed the singer and actress since April 2010 in a nationwide ad campaign.

The questions were written by Cook County Judge Charles Burn, who will preside over the trial.

Attorney Troy Slaten represents neither defense nor prosecution, but explained why Hudson's good intentions may compromise a verdict's purity as much as her fame (though she can't help it) may already impact jury selection. E! claims to have confirmed that Hudson's name is listed among the 300 or so potential witnesses that might enter sworn testimony.

"Star power always matters," Slaten said. "The prosecutor wants her there and the defense does not want her there. The jury could be looking at her reactions, if she is crying, how she reacts to certain testimony. They are going to be very aware of her presence."

Slaten added that despite the chance a mistrial could be declared, the prosecution may consider Hudson's involvement "a risk worth taking."

Balfour, meanwhile, has served a previous seven-year sentence for attempted murder, vehicular hijacking and possessing a stolen vehicle.
