I told her, 'Touchdown!'"This was such an important performance because it's the first time everyone has seen Jennifer. But she's in such a great place, with such great spirits and time can heal her wounds. She's on fire right now and totally grounded."Jennifer's estranged brother-in-law, William Balfour, 27, has been indicted on murder charges for the triple killing of the singer's mother Darnell Donerson, brother Jason Hudson and her nephew Julian King, the son of Jennifer's sister Julia.
