The singer-and-actor recently spoke to Jennifer - who is recovering following the murders of her mother, brother and nephew last year - and has revealed the pair may perform a series of concerts together.
He told ET Online: "She's doing well. She says she wants to get back into the flow of things. Hopefully we will go out on tour together and, you know, heal the world with our music."
Jennifer, 27, made her first public appearance since the tragedy at yesterday's (01.02.09) Super Bowl, where she sang the US national anthem. Despite looking nervous, her rendition of the 'Star Spangled Banner' was so powerful fans at the prestigious American football match - which is watched by millions all over the world - gave her a standing ovation.
Pre-game show producer Rickey Minor, who worked with Jennifer on US reality TV show 'American Idol' and booked her for the Super Bowl, said: "She came of stage and said, 'How did I do?' 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.
