Jackson has previously spoken out against Murray and blamed the physician for the singer's death, telling talk show host Oprah Winfrey, "Yes, I do (blame him). He's the one that was administering the drug, from what I do know."
Murray has pleaded not guilty to the charge and will go to trial on 28 March (11) - and the Nasty hitmaker insists she will be front and center in the Los Angeles courtroom with other grieving members of her famous family to witness proceedings.
In a candid TV interview with journalist Meredith Vieira, she says, "It's tough sitting in the courtroom.
"(But) it's my brother, it's my blood, he's no longer here because of X, Y and Z. I think it's important to every family who's lost someone (to attend court). You want to see justice."
A preview of Jackson's interview aired on the Today show on Friday (11Feb11). The full chat will be broadcast on news program Dateline on Sunday night (13Feb11).
