10:45 AM PDT -- Jennifer has taken the stand and will testify in the case.


The man accused of murdering Jennifer Hudson's mother, brother and nephew goes on trial today, and Jennifer just showed up.

William Balfour stands accused of the slaughter, and prosecutors believe the trigger for the carnage was a balloon gift for Julia Hudson, Balfour's ex and Jennifer's sister.  Prosecutors say Balfour thought the gift was from Julia's new boyfriend and it sent him into a blind rage.

Opening statements are set for today. Hudson is on the witness list but it's unclear if she'll testify.
